I have finished the left and right drive units. I'm not entirely pleased with how they turned out, and I'm pretty sure it's due to the issues I've had trying to get PETG to print without warping off the bed. There's a bit too much slop in the gears in my opinion.

I'll have to decide whether to reprint the entire assemblies, and what filament to use if I do. I know I can print PLA+ with no issues, so that may be what I end up doing. I'm also having better luck with PETG after turning the part cooling fan completely off and using a different textured print bed. I might have enough PETG left to try reprinting one of the gears. If I reprint a gear and it has a tighter fit for the bearing, I'll buy another spool of PETG and reprint all the gears and go from there.

For the time being, the drive units work and will be good enough until I get to the point where I add motors to them.
