Wood-chip Hoppers in N and TT


I’m adding some wood-chip hoppers to the line of TT and N models available at Shapeways. These models feature sides separate from the frame to improve the smoothness of the print and to ease the cleaning/sanding prep work. They are complete other than gluing on the sides to the frame, adding trucks, and they require building the side ladders using scratch building materials like styrene and wire. Shapeways recently changed their design restrictions, so they now refuse to print fine details like ladders unless they are of a certain thickness. Consequently, the viability of printing certain details like ladders while still looking good has diminished.
