rspraguepci@train_guy OK, the design was really easy. I put some up on the shop for you. I think they might look good in "Black Strong & Flexible" plastic -- it has a rough texture that might simulate the real material, plus it's cheaper than the FUD.
rspraguepci@train_guy Glad you like the stairs! Have fun. I had thought about doing some door bellows. I wasn't sure the 3D material would really look like the kind of vinyl/canvas material of the prototype but it would be easy enough to do the shape.
