Planetary gearbox

OpenSCAD planetary gearbox. Repo at https://github.com/Erhannis/gearbox . A port of one of Gear Down For What's gearboxes: https://www.thingiverse.com/thing:2054378 . His is licensed under CC/A/SA ; I don't know what that makes mine. Mine is otherwise MIT licensed.

Run get_deps.sh to get the dependencies from github. If you're running windows, install git, make a "deps.link" folder where you have the gearbox scad, then in that folder run the "git clone" lines of the "get_deps.sh" file. OpenSCAD should be able to read gearbox.scad properly, then.

Oh, and flattedShaft is just a test crank. Didn't have anything around that fit quite like a stepper motor shaft. (If anybody knows where to buy 2.5mm radius D-shaped shafts like that, I'd be interested in buying some, btw.) The "long" stls are modifications for increased strength for my paste extruder (https://www.thingiverse.com/thing:4182973).

Printing: I used 0.2 layer height, 20% infill. Cura's "Standard Quality" setting
