Your designs are getting a lot better - keep up the great work!
The standoffs that hold the gearbox together are 10-32 tapped, so you can just screw the plates on. The front view of the gearbox shows these are countersunk, but that's because I wanted a single style of plate to work for both sides (in real life you would just not countersink the front side).
The module gear is because there are no good diametrical pitch gears available.
Thank you!

Also, I forgot to mention that the weight is 1.6lbs as shown, which can be reduced by lightening the 60t gear.
