Windows, doors, columns, cornices, and chimneys.
I first built a window with 3D Studio Max so that I could get a 3D print of it and cast that. But for some reason Max has issues with Shapeways and et al.
So the heck with it! I'm going to build them up with styrene. These things are tiny in HO scale, I had to apply the cement with a syringe!
I think I've got everything. The next step will be to make a rubber mold of these and then I can cast as many bits as I need.
Yes sir! Cast as many bits as I need!
