Drop Bottom Wooden Ore Hopper (F scale)

This is a rework of a wooden hopper plan to upscale it from 1:22.5 to 1:20.3, Fn3 scale. It uses my archbar trucks and 24" wheels: https://www.thingiverse.com/thing:2929708 and raby's nifty knuckle coupler with the boxcar type box https://www.thingiverse.com/thing:1908821 . I included an STL of the assembly to date but be aware that it is still being refined and added to.
