Modular 12mm sci-fi buildings

Loosely based on the papercraft buildings designed for Heavy Gear Blitz, these stackable buildings are 1/144th scale and made to hold 12mm infantry inside. Combine them however you like.

The "Base" and "Shops" (as well as their Doubles versions) are designed for ground level, while the "Apartments" and "Offices" are designed for upper levels, with the "Roof" models obviously for the top. You can line the stairs up for maximum aesthetics, but the pieces will fit fine when rotated other ways.

You shouldn't need supports for this (at least on an FDM printer). I printed mine at 0.3mm and had minimal cleanup, but I'm also terrible at calibrating my settings.
