I spent an hour setting up a parametric design so I can easily change dimensions on the fly.
The main goal today was shrinking the overall footprint. I need the entire assembly to fit inside a 56mm parallel plate drivetrain. The wheel takes up 38mm and the two side plates are 6mm each. That leaves very little room to fit the gearbox internals and the outer cage.
I spent the session making all the gear layers and housing walls much thinner to squeeze into that remaining gap. Since the parts are getting so thin, standard printing might fail. I am now looking into SLA printing for these parts to make sure the fine details and tight tolerances actually hold up.
