designed to link foam core, or corrugated plastic slats together to make buildings. Basic hinges that use 1.75mm filament as pins. The wall toppers give a little more depth, and hold cut sections for roofing.

Ideally, you should be able to pop the roof and fold the building flat for storage afterwards.

eventually I plan to make door and window frames that push mount to the walls for quick design, and stairwell toppers to accommodate multiple floor buildings.
