G-Scale Super Chief Mail Car

This is one of several "things" that I have been working on for a Super Chief style train in G-scale. (not 100% accurate, but close enough)

Update: 15th April. End door remixed to fit better.
18th April. Hole in base for bogie bolt needed to be just a little bit bigger. Fixed

It could probably be down-scaled (everything) to run on 32mm track, bearings would have to be considered... but I doubt you could make the mechanism work in OO

Inspiration from https://www.thingiverse.com/thing:4796985

I used the rear end for the profile, did a bit of resizing and remixing to it, also used the chassis, with modifications and fixes and a modified from the F7 located at:

All other files have been re-drawn completely and an imaginary interior designed for it
I have not printed this yet, so any problems will be corrected as I print.
