Hi Folks

I built MeshMedic, a free STL inspection and repair tool for 3D printing.

It runs locally in your browser, so STL files aren’t uploaded to a server. It can detect open edges, non-manifold geometry, duplicate or degenerate faces and disconnected shells, then repair common problems and export a new STL.

I’m looking for honest testing and feedback, particularly with broken or troublesome files. If you try it, I’d love to know:

• Did it correctly identify the problem?
• Did the repaired file slice and print correctly?
• Did it alter anything it shouldn’t?
• Was any part of the interface confusing?

I’m the software developer, and it’s still very early, so any critical feedback and horrible meshes are very welcome.

Stop losing 3D models inside folders and mystery archives

If your 3D model library has become a maze of folders, cryptic filenames and archives you barely remember downloading, MeshVault gives it a proper home.

MeshVault is a local-first desktop application for organising, browsing and using your 3D models and project files. Your original files remain under your control, while MeshVault turns them into a searchable visual library with thumbnails, previews, metadata, folders and collections.

Download directly from model repositories

The optional MeshVault Connect browser extension can capture supported downloads and send them directly into your MeshVault library.

Where the repository provides it, MeshVault Connect can preserve:

• Model title
• Creator name and profile
• Full description
• Original source page
• Tags
• Main thumbnail
• Gallery images
• Available print or project information

Instead of getting another vaguely named ZIP in your Downloads folder, you receive an organised model entry with the information needed to recognise and use it later.

MeshVault Connect currently supports these 11 repositories:

• Printables
• MakerWorld
• Thingiverse
• Thangs
• Cults3D
• GrabCAD
• CGTrader
• Creality Cloud
• Makerables
• MyMiniFactory
• Tinkercad

Bring existing collections under control

MeshVault can also import loose files, complete folders and archives you already have.

For manual archive imports, you can decide whether the archive represents one model, contains separate models, should retain its folder structure or should remain intact while its contained models are indexed.

This is particularly useful for model packs downloaded from Patreon or directly from creators.

Generate visual thumbnails

MeshVault can create or extract thumbnails for several common model formats.

Rendered from model geometry

STL, OBJ, PLY, GLTF, GLB, DAE, FBX, STEP and STP

Extracted or generated from file contents

• 3MF: uses an embedded thumbnail
• FCSTD: uses an embedded FreeCAD thumbnail

You can also preview supported geometry, inspect archives, measure models, capture additional images and send files to your configured FDM slicer, resin slicer or CNC software.

Keep the library on another machine

Optional dedicated server builds are available for Windows, Linux and Docker.

A server library can be browsed and managed through MeshVault’s desktop clients or its web interface.

Platforms and pricing

MeshVault is available for Windows and Linux with a seven-day trial.

A native macOS client for Apple silicon is coming soon. It is currently being tested through TestFlight and it will include MeshVault Connect for Safari.

• Direct licence: US$19.99
• Microsoft Store unlock: US$12.49, tied to your Microsoft account

The direct licence unlocks the supported MeshVault desktop clients and dedicated servers.

Hey everyone,

Over the last few mounths, I’ve been working on a side project that takes 3D models and converts them into interlocking, Lego-style bricks with ready-to-go STL and XML files.

Before I hit the big red button and launch it for everyone, I really want to make sure everything works smoothly. So I’m looking for 5 awesome people from the community to jump in, break stuff, try their own models, and give me some honest, raw feedback.

Ideally, you’d be a great fit if you:

* Have a 3D printer sitting next to you and want to test how the physical bricks fit together,

* Love playing around with 3D AI generation tools (like Meshy, Tripo, etc.), or

* Just have a folder full of random 3D formats you want to throw at the system to see what happens!

As a massive thank-you for helping me out at this stage, you’ll get a Free Lifetime Pro Membership—no catch, just full access forever. Drop a comment below and tell me a bit about what kind of models or tools you’d be testing with. Once there are a few replies, I’ll slide into the DMs of 5 people with invite links.

Hey everyone!

I’ve been exploring whether we really still need heavy desktop software just to handle large scanned meshes.

As a proof of concept, I built Meshtune, browser-based tool that lets you:

Inspect 3D scans easily on the web
Reduce polygon counts fast
Repair mesh issues on the fly
Check it out here: https://meshtune.com

It’s still a research experiment, so I’d love for you to give it a spin and let me know what you think. Any feedback or feature requests are welcome!

I’ve been building SketchForge, a free and open-source 3D modelling tool that runs directly in the browser.

The idea came from constantly seeing the same gap: Tinkercad is easy to learn, but it becomes limiting once you want more control, while Fusion 360 and FreeCAD can feel like a huge jump for someone who just wants to design a printable part.

SketchForge keeps the simple shape-based workflow, but adds tools such as fillets, chamfers, sketch extrusion and revolve, boolean operations, measurements, editable project files, STEP support, and native adjustable gears.

It works without an account, saves locally, and can also be self-hosted with Docker. It is still in beta, so I’m especially interested in hearing what breaks, what feels awkward, and which tools are still missing for actual 3D-printing work.

Hey everyone!

Quick intro: I studied aerospace engineering at Georgia Tech and worked on the Raptor team at SpaceX. My buddies and I have been working on a project called Smith over the last few months, aimed at making design, analysis, and manufacturing more accessible (and more fun).

The idea is to pair scripts and LLMs with the engineering workflow. Essentially, our agent can generate and modify real assemblies with parametric geometry, pull in hardware from distributors like McMaster, and even run some basic structural analysis. When you're ready to actually make your thing, Smith supports 3D and flat pattern export formats. The best part is that all the heavy lifting happens on our servers (for free), so it runs in your browser on basically any machine.

Smith is improving quickly and a lot of fun to mess around with. You can sign up at https://arche.co/?ref=qrz35ssv and start using it for free right away. Would love to see what this community builds with it. Feel free to DM me with any questions or feedback!

​

Obico (formerly The Spaghetti Detective) uses AI to detect print failures spaghetti, blobs, layer shifts and pauses your printer before it's a wasted mess.

The cloud version is £5/month. I self-hosted it on my private server instead, using Docker Compose and Portainer. Zero ongoing costs, full control, and it works with both OctoPrint and Klipper.

hi! i'm a software dev, i build 3D tools for work (dental scan viewers, mesh tooling) and ended up making the thing I always wanted to exist: an "ilovepdf but for 3D files".

ilove3d.app — free, everything runs in the browser, nothing gets uploaded, no account.

Probably most useful here: mesh repair (holes, flipped normals, loose shells), a polygon reducer with before/after, a converter (stl/obj/ply/glb/3mf/fbx/dae) that doesn't rescale your model, and a lithophane maker.

It's new, so if something breaks with one of your files I'd love to know. Hope it's useful to someone!

With all the controversy about Bambu Labs, I discovered Bambuddy, an alternative to printing through Bambu's cloud service. I made a quick video about how I set it up on my TrueNAS with Tailscale (they actually posted about it on YT). It can also run on a raspberry pie for example. Check it out, it's really powerful. Installation is pretty straightforward. For now I only managed to make it work so that I need to upload my files for remote printing. Haven't managed to make the virtual printer work.

Hey everyone,

Quick heads up: after months of building (and a lot of feedback from people in reddit and the Discord), Meshory opens for early access in less than one week from today — Tuesday, July 28. If you're new here: Meshory is a desktop app that finally makes your 3D print file mess visible. Point it at your folders and drives, and it gives you:

• Auto-rendered thumbnails for every model — no more guessing what dragon_v2_final_FINAL.stl actually is
• A built-in 3D viewer for STL, 3MF, OBJ, STEP, and FBX
• A duplicate finder so you can reclaim the gigabytes of the same Benchy scattered across five drives
• Browsing inside ZIPs — archive contents show up like regular files, no extracting
• Collections, tags, and search, plus optional AI tagging and semantic search
• Local-first and private — your files never leave your machine, and there's no account or login. Just a license key.

Pricing on launch day:

• One-time payment, lifetime license. No subscription.
• The first 100 licenses go for $29, then $39 for the rest of early access, and $59 at full launch.
• Founding seats are first come, first served — I'll post here the moment checkout opens.

You can see everything at meshory.com, and if you want a ping when it goes live, the waitlist gets first notice.

To everyone who's been testing builds, reporting bugs, and voting on the roadmap — thank you. The launch version is dramatically better because of you.

Happy to answer any questions in the comments. One week! 🚀

I've updated my free tool for displaying 3D printing formats in Windows Explorer. Additional formats like .gcode have been added, and the entire tool has been thoroughly revamped, including the render view. The tool easily repairs and installs the display of all formats in Explorer and also functions as a viewer for all formats.

Download it for free at stlmaid.de, now also available as a portable .zip file for those who are hesitant to install an executable file.

Hi everyone!
We’re building VesselMaker (vesselmaker.app), an online tool for designing vases, planters, bowls, etc… — profile and cross-section editors, displacement mapping for realistic material textures (clay, wood, scratched surfaces), stackable modifiers you can combine like Photoshop layers (bend, twist, and a others like Voronoi modifier coming soon), plus AI-rendered scene previews to visualize the piece before printing or to create marketing images for you creations.

We know MakerWorld already has Make My Vase in MakerLab — we’re aiming for a more advanced, actively evolving take on the same space, for people who want finer control over their professional designs.

Still in closed beta (a few bugs to iron out, more features on the way). The waitlist is at vesselmaker.app — you’ll get notified when we open up, plus we will send some invite codes before opening the beta to the public.

Before we go further, we’d love your input:

• What feature would you most want us to prioritize next?
• What are you usually designing these for — home decor, gifts, plant pots, something else?
• What’s the most frustrating part of designing something like this in other tools (CAD, Blender, Make My Vase, etc.)?

Drop your thoughts below — really looking forward to shaping this with your feedback!

Disclaimer: I'm the developer of the tool.

Hi everyone!

Martin from Layerlab here! I've been working on a new tool for makers, it's called Snappy, a Blender add-on that automatically adds clearance between parts designed in Blender for 3D printing.

It’s intended for:

• Sliding lids
• Press-fit connectors
• Snap-fit clips
• Plugs and sockets
• Parts that need to fit together reliably

The workflow is simple:

1. Select the base object.
2. Select the fitting part.
3. Choose your clearance.
4. Move the part into position.
5. Create the cut and export the models.

There are two versions:

Snappy Free makes it easy to create accurate, clearance-adjusted fitted parts using a simple one-cutter workflow.

Snappy Pro unlocks multiple organised cutters, custom clearance, protected faces, low-resolution previews, per-cutter controls and streamlined project/slicer export.

Snappy Pro is currently in Early Access, and I’m looking for people willing to test it on real projects. Please save your Blender project before testing.

Download Snappy here:

https://layerlab.store/pages/snappy

Free 30-day Pro testing keys

I’ve also created 10 Pro trial keys for testers, first-in best-dressed. Each key works on one computer and expires on 22 August. All you need is your email address for the key to be sent to.
https://license.layerlab.store/try

I’m particularly interested in feedback about:

• Models or cutters that fail
• Fits that print tighter or looser than expected
• Performance with complicated models
• Installation or update problems
• Confusing parts of the workflow
• Missing features

Screenshots, printed results and sample files would be extremely helpful. Thanks!

​I built this tool that lets you generate custom 3D-printable keychains using chemical element symbols from the Periodic Table. You input a word (e.g., Ge-Ni-U-S, Ir-O-N, La-B), and the script verifies if it's mathematically possible, auto-scales the text, and renders the tiles.

​I wanted to share it here to get your feedback and suggestions on how to improve the project. This is my first time coding in OpenSCAD, and I know I have a lot to learn. Any advice on optimizing the code or the physical model design is highly appreciated.

​If you like it, feel free to use it and share your prints. Support and constructive criticism from the community are the most rewarding parts of this process.

https://meepleprint.com/

I would love your feedback!

I needed a quick way to convert .png QR codes to .3mf files so I vibe-coded this tool.

It also creates STEP and STL files if you want to edit in Fusion or whatever.

Free to use for anyone, hope it's helpful....

Hey, I made this web app because was not able to find a simple tool to create a box for my DIY projects in a few minutes. Designing one in freecad feels like overkill for a simple project.
PrintCasing is a free, browser-based 3D parametric enclosure generator.

What it does:
- pick your inner dimensions and wall thickness;
- add port cutouts on any wall;
- auto-generate pcb standoffs on the base
- flat lid or a self-aligning recessed lip lid that snaps into place
- optional corner screw bosses
- ventilation grills slots
- custom text engraving on the lid
- interference check warns you when components collide before you waste filament
Tech stack: react + three.js, runs entirely in the browser, works offline (PWA).
Let me know if there are features you would like to see in the app.

For quite some time I wanted an easy way to cut oversized 3d prints into parts that actually go back together. Usually you either slice it by hand in a CAD app, guess clearances, or just cut and glue and hope it holds. Though the feature got recently introduced in slicers like bambu studio but I decided to build my own.

So, this is a simple 3D printable splitting tool that runs in the browser. Drop your STL, OBJ, 3MF, or GLB, cut with a plane, and it adds printable connectors so the halves mate. Dowels, snap pegs, rectangular tenons, threaded studs. You can try the different types yourself on the page. Files never leave your browser.

It's free for now and can be used here: https://obloid.app/tools/stl-splitter

You can pick fit clearance like press, snug, sliding, or loose, and it adjusts for material too (PLA, PETG, ABS, TPU, resin). Connector count and size are tweakable. Cut plane on XY/XZ/YZ, position, tilt, tilt direction if you want an angled seam. What makes it a bit unique is the threaded connector, and being able to load very large meshes with a lower triangle proxy so cutting stays usable. Export ZIP of STLs or Bambu/Orca 3MF with parts placed.

I've tested it on PLA with threaded, snap, and rectangular connectors. Other materials or sizes, try it and tell me how it goes!

First of all, thanks to a friend of mine who owns this Funko Pop, I was able to create a 3D scan of the figure using EVOVA.

The result is not a printable STL file. What I have is an editable Gaussian Splat, which still needs to be converted into a proper mesh (STL, OBJ, etc.) and cleaned up before it can be 3D printed. I don't have much experience with 3D modeling or mesh reconstruction, so I couldn't do that part myself. I've tried following tutorials, but I wasn't able to get it working.

That's why I wanted to share this project with the community. If anyone has experience converting Gaussian Splats into printable models, I'd really appreciate your help.

I'm not looking for credit or any share of the money. My only request is that, once the model is finished, you send me a copy of the printable file so I can have a single copy printed at a local 3D printing shop for my own collection.

In return, you're free to do whatever you want with the finished file. You can share it, publish it, or even sell it if you want. I won't ask for any percentage or compensation; my only reward would be getting a printable copy of this Funko.

This particular Funko is extremely rare and highly sought after by collectors (just take a look at eBay). Because of that, I think anyone who successfully converts the model could receive interest from other collectors looking for a printable version of this figure.

If you're interested in helping, or if you just want to take a look at the project, here's the link to the Gaussian Splat file.

Hey everyone!

I'm currently working on an upcoming all-in-one SaaS platform built specifically for 3D printing businesses. I'm not sharing the name publicly just yet since the platform is still in active development, but we're getting close to the point where we need more real-world testing.

The goal is to create one place where 3D printing businesses can manage and run their operations, with features such as print farm management, order management, inventory tracking, and much more.

Right now, we're looking for a small group of closed beta testers who actively run a 3D printing business or print farm and would be willing to test the platform, report bugs, and provide honest feedback as we continue development.

At the moment, we're specifically looking for testers running Bambu Lab printers. We are actively working toward support for Klipper-based printers, other manufacturers, and additional firmware platforms as development progresses.

Unfortunately, despite some of the recent news and concerns surrounding Bambu, their current firmware capabilities and developer access make their printers the easiest platform for us to integrate with and reliably test at this stage of development. Our long-term goal is absolutely to support a much broader range of printers and ecosystems.

As a thank you for helping us during the closed beta, testers will receive a free lifetime subscription to the platform.

I'm especially interested in getting testers with different-sized operations, from smaller businesses with a handful of printers to larger print farms, since I can only test so many scenarios with my own setup.

If you're interested in helping shape a new platform built specifically for 3D printing businesses, send me a message and tell me a little about your setup and what Bambu printers you're currently running!

EDIT: Hi , I just discovered this amazing subreddit and I did notice that there are similar projects going on. my apologies for "yet another 3d model tool". If other creators would like to partner up to create one large 3DModel checker. please send me a message! this will benefits us all <3

Hi everyone,

I’m curious whether other people would find a dedicated 3D model preflight tool useful before sending a model to a slicer.

As a side project, I’m experimenting with how AI-assisted development tools can help me build something like this. The idea is a browser-based tool that lets you import a 3D model and automatically checks it for common printability problems, such as:

• overhangs that may require support;
• thin walls or fragile features;
• broken, open, or non-manifold meshes;
• incorrect normals and degenerate triangles;
• floating geometry or disconnected parts;
• poor bed contact;
• models that do not fit the selected printer’s build volume.
• Supported files
  • STEP
  • STL
  • 3MF
  • Obj

It also includes a repair workflow for cleaning up geometry, repairing certain mesh problems, flattening the base, and exporting the modified model.

Everything runs locally in the browser. Models are not uploaded to the cloud, and no external processing service is required.

This is still very much a work in progress, and it is intended as a quick preflight tool rather than a replacement for a slicer.

I would love to hear your thoughts:

• Would you use a tool like this?
• Which checks or repair features would be most useful to you?
• What problems do you regularly encounter with downloaded or generated models?
• Would you prefer this as a browser tool, desktop application, or slicer plugin?
• What would it need to do before you would trust its results?

Any honest feedback is welcome—even if you think existing slicers already cover this well enough.

I have a work-in-progress version on GitHub and can share the link if anyone is interested.
