BH2 Parts from the Empire of Dirt Workshop

Note: Because the actual components, which are made in black plastic, are difficult to photograph, the component images in this section are idealized computer renderings, rather than photographs, to illustrate the physical geometry of the various parts.

The STL files for the following parts may be freely download for personal, non-commercial purposes.  If you don’t have access to a 3D printer, please contact me.
