This is a sample set of modular 3D printable building components designed for FDM printing without the need for supports. The system uses a lock wall mechanism with channels on perpendicular walls to connect pieces, along with matching floor and roof footprints.

By combining different pieces with matching openings, users can assemble small sheds or larger customized structures. The files are provided at 1/100 and 1/72 scales, and the set includes a sandbag roof piece alongside a PDF instruction guide.
