Standing seam roof for signal box

thingiverse

I wanted a compact structure for my yard office in an N Scale yard scene that I'm building. A precise prototype was less crucial than simply a believable structure. I've been impressed by Badgerbreath's models so I decided to use his signal box model. The roof proved to be a challenge. The corrugations did not print well in N Scale, and the signal tower that I had already built for the yard featured a standing seam roof. So I designed a standing seam roof with the same seam spacing as my tower. This led me to printing a HO version to test the new roof out. The seams are pretty wide in HO, but I wanted something that would be printable in N Scale. Photos of both the HO and N Scale signal boxes can be seen here. The HO was printed at .12mm layer thickness with a .4mm nozzle size. The N was printed at .08mm layer thickness, using a .3mm nozzle size, scaled to 54%. One photo shows the N Scale model alongside the Tichy (ex-Dimi Trains) tower. After taking the photos, I noticed that I had glued the HO roof on incorrectly. Oh well.
