The Modular Commo Building is a highly versatile set of STL files allowing you to build out your base infrastructure quickly from your own 3d printer. Designed in the style of authoritarian governments across the galaxy, it fits right in as a terrain piece for many sci-fi tabletop wargaming themes.

Use just the ends together for a small building with a high roof, which has ladder access and stair access to the lower level roof. Add the modular frame and roof sections to create a playable multi-level building, playing through on the floor level, ladder and stairwell access to the first floor roof, as well as a nice high perch for units with range on the Commo Tower end.

Designed for 32-34mm wargaming, a great piece of modular terrain that allows you a ton of flexibility in your structure builds. Scale up or down for different game systems.

Uses 8mm x 1mm Magnets for roof sections, easily found on

Modular building

Prints great and love how it fits together. The magnets worked great to connect the pieces together.

Super good terrain piece

I needed something for a spacefighter landing pad that would also block line of sight for our Imperial Remnant fighter base table - this piece is perfect! The flat top is big enough to park any ship on, and it's super-playable, with ladders and stairways on both ends. I've printed four of these so far on my Ender 3s. My only suggestion for printing them is to print the frame with a substantial infill - I went with 50% - otherwise the thin legs are very brittle. This is partly mitigated by gluing it all up, but better safe than sorry.

Overall, a great piece!

Great stl file.

Printed this off on an ender 3 and am now working on painting it. It looks amazing and I love that it can be configured in different ways.
