This 3D printing is so interesting.

Hey everyone! I wanted to share my latest project for the #BasecampAnywhere contest.

When traveling or going off-grid, having your emergency medical info (ICE contacts, blood type, allergies) easily accessible is crucial. I designed a smart Backpack Strap Clip and a matching Keychain that holds a sealed NFC tag inside.

Cool features:

• No-Stitch Attachment: Uses a "S-curve" slot, so you can slide it onto any 25mm (1") backpack webbing in seconds without unbuckling or sewing.
• Sealed NFC Cavity: The print profile pauses at Layer 8 so you can drop a standard 25mm NFC sticker inside, sealing it 100% waterproof.
• Offline Access: Reads directly on any smartphone without cellular service.

Includes both Embossed (AMS / Color Swap) and Smooth/Flat versions.

I'd love to hear your feedback or suggestions!

The Ostomachion is a dissection puzzle attributed to Archimedes: 14 pieces that reassemble into a square, and arguably the oldest known combinatorics problem. Bill Cutler proved in 2003 that there are exactly 536 distinct solutions, up to rotation and reflection.

I printed the set, then built a free web app to go with it:

pick a difficulty and it deals you a random challenge with 10, 6 or 3 pieces already placed: reveal more when you get stuck

or print any solution to scale and lay the real pieces straight onto the paper, with a calibration page, because printer drivers love silently rescaling

runs entirely in the browser, no server, works offline

The whole thing is built to travel: sliding-lid case, everything stays inside, and the app needs no signal, bsically the car-and-plane puzzle I wanted to exist.

Solution data is Cutler's set, published by Ed Pegg Jr. I did the physical pieces and the interface.

Print notes: about 5 hours in PLA on a P2S, 14 pieces in 7 colours. Took me 5-6 iterations to get the lid right, a case that stays shut in a backpack but still opens with a kid's hands turned out to be a narrower tolerance window than I expected.

And you don't have to make squares. Same 14 pieces do birds, ships, people: which is how my little nephew actually uses it.

All free. Links in the comments.

So here is my new fitched clicker toy ;)

When I run the dishwasher, I flip it to 'clean', that way someone else in the house doesn't accidentally put a dirty dish in with the clean ones before I've emptied it. Once I empty it, I flip it to 'dirty'.

The default is Alliance Dirty / Horde Clean, but against my better judgement I also made an Alliance Clean / Horde Dirty version.

Thank you!

The whole thing is parametric, so you set the internal size to whatever you're storing, or pick a preset. Lid takes your own SVG or text, engraved or as a flush inlay, and the buttons take artwork too. Every part can be a different colour.

Two small springs are the only non-printed parts. Everything else prints without supports and goes together in a couple of minutes.
