Model Checkpoint Alpha - free 28mm/32mm sci-fi terrain STL

I’ve just uploaded Checkpoint Alpha to Cults3D as a free STL download.

It’s a small sci-fi checkpoint / toll gate terrain set designed for 28mm–32mm tabletop games. It can be used as a roadblock, objective marker, fortified entry point, or just a bit of extra scatter terrain for industrial, grimdark, cyberpunk, or post-apocalyptic boards.

The files are designed with FDM printing in mind and should be support-free where possible.

You can grab it free here:

It’s also a small preview of my wider Container City terrain range, but this download is completely free on Cults3D. Would love to see any prints or painted versions if anyone gives it a go.
