Bafang 500C-H display holder stem mount round and square

A modified mount for Bafang 500C-H display.

You need to punch out the stock pin and replace it with this part. My stem is 38mm by 33mm and the mount takes 2 additional M4 12–16mm screws. You don't need to insert the pin back, but if you want to, you might need to use 2mm drill bit for the pin hole in the printed part.

Added 32mm round holder. Integrated print in place pin, 0.25mm horizontal clearance, 0.4 vertical clearance. M4x14 screw minimum.

Added 22mm.
