Remixed from https://www.thingiverse.com/thing:5454437

I made the truck mounting areas thicker and made the holes bigger to use Micro-Trains trucks with couplers. I used medium shank but you can clearly use short shank for a cleaner look.

Would be cleaner printed on a resin printer but prints fairly well on an FDM printer with ultra fine settings as well.
