+1000. We are getting sidetracked. Any discussions about 3D printing might be kept to another thread. OP should do the research and decide that way if the teams wants to print.
Anyway, my post above asked a few questions about this gearbox.

EDIT:
The questions from ym last post:

1. What is the final weight of this gearbox without motors?
2. What is your reasoning for going with a bevel gear setup?
3. What advantages does this design hold over 192's gearbox design from 2014? I still haven't seen a shifting gearbox design that beats theirs in terms of weight or size.

20fps is too fast. You can limit the top speed in software for the driver, but your acceleration will be very poor with only 4 cims. Seeing as you are running bevel gears, would it be possible to add a 3rd cim sticking stright up?
Your final gear reduction looks like it can be reduced to a much smaller/better ratio. Top speed for a 4 cim drive shouldn't hit above 17-18fps if you want to optimize distance/time. OC it depends on the game, but it would be a very rare game that requires 20fps on four cims.
