Design Comment

I think the previous poster has the same thought, but your center CIM gear between the two other gears is asking for trouble. There will be some manufacturing tolerances and it will mesh well on one side and poorly on the other side and probably shred the gear teeth. No Fun.

Since you seem to like designing gearboxes - what about one where you are trying to keep CG low by keeping the CIMs at or near the same distance from the ground that the drive axle is? Probably not the most useful as you are only lowering the CIM a few inches, but would be fun to see what you come up with!

SolidWorks Comment

I like that you included your SW files, but you did not include them all. This is a common enough problem that SolidWorks has a feature for it called "Pack and Go" under the File menu. It allows you to take an entire assembly and copy all the parts. You can flatten them to a single folder (recommended) and even ZIP them up, all in one step. Great for sharing whole assemblies while keeping them in SW formats (instead of STEP).
