pic: One robots worth of gears

I know the little raised surface on the gear only extends out that far, but that part of the gear isn't sized that way for strength; it's sized that way to interact with bearing races.

This is more gut paranoia than actual analysis though; perhaps you'll be fine.

Other than that, looks great. Gear lightening is an often overlooked way to save some pounds.

Looks pretty similar to hub size on gears we've pocketed previously. Obviously the loading matters but it's probably not a huge concern.
