About this model

This is a freelance G-Scale (1:22.5) 20ft Flatcar for 3ft Gauge. This is an untested prototype. I'm posting it here so that others can try it on their printers and report back valuable data on how well it prints and what might need to get tweaked going forward. If you remix this model, please let me know, I'd love to see what you make with it. You will need to add some 3mm x 10mm x 4mm ball bearings to hold the axles in their slot. A link to recommended bearings is included below. You will also need a 2mm metal rod to hold the Brakewheel. A link for recommended rods will also be included below. You will need to figure out the wheels yourself. This design should easily accomodate the generic Bachmann Big Hauler Boxcar wheels. Ball Bearing Link: 2mm Metal Rod:
