N Scale Clerestory Roof for Old Farish Coaches

thingiverse

Replacement clerestory roofs for old Farish N scale coaches. Four variants covering the suburban coach and brake-end, plus the 4-wheel coach and brake-end. I'll see about painting them in a few weeks, and will update this entry then. Designed in OpenSCAD for the FlashForge CreatorPro, in ABS with default settings, no raft or supports required. The press-fit base is a separate piece so that the edges of the roof can lie flat on the print bed to give a clean straight edge. Caveat: While building these I discovered that my printer's length calibration is out by about 1%. The STLs are correctly scaled for my printer, so you will probably need to rescale slightly in X to get them to properly fit onto the bodies. A trial build will make this clear - the roof should be about 0.3mm longer than the body length, giving a very slight overhang at each end.
