8 axle flat car in N scale

thingiverse

This is an 8 axle flat car based on the QTTX 130556; http://www.solrswat.ca/1_EquipmentRoster/Freight/TTX_QTTX_Flats/8_axle_FD/QTTX130550-130556.htm This heavy-duty, drop-deck flat car is used for transporting very heavy and tall loads, often transformers or large machinery. To complete this build, you will need 4 N-scale Intermountain trucks and a pair of brake wheels. Build one deck, two bolsters, and four pins, using the pins to attach the trucks. Use 1.75mm filament to secure the bolsters to the deck. Note that there are two sets of STLs available, with the ones ending in "HQ" being high-quality renders with more details designed for printing on a Formlab (or similar) machine, which may not print well on a typical FDM printer. The triangle code is credited to Tim Koopman; https://github.com/tkoopman/Delta-Diamond/blob/master/OpenSCAD/Triangles.scad Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: No Supports: Yes Notes: To print the deck, use it on its side and do not add support. The bolster is more challenging to print and requires support; however, MakerWare does not handle this well. Use MeshMixer supports successfully. Post-Printing Assembly Cut off the couplers from two trucks. Attach the four trucks to the bolsters by pinning them in place. Place a short piece of filament in the holes on the deck. You may want to use super glue for added security. Pass the filament through the bolsters and melt the ends, mushrooming them so that the bolsters do not fall off. Securely attach the brake wheels to their stands, ensuring they face inward toward the deck.
