Two stage gearbox, 7.7:1 ratio (parameterized) by tkbletsc

** Update: I forgot to include my custom general purpose library, tyler.scad. I just uploaded it.
I'm working toward a general multi-stage customizable gearbox to accept a variety of motors, and this is my work so far. My ultimate goal is a gearbox system where you can put in the parameters of any junk DC motor you have and have it generate a gearbox+motor mount suitable for hobby robotics.
I haven't tested or finalized the parameters, so I'm not going to turn on customizer support, but if you download the OpenSCAD file, you should be able to tune it fairly widely.
It's fully 3D-printed, except for some #6 or M3 screws to hold it together (basically any PC computer case screw).
It works decently well. Right now it has pegs for the input and output gears for testing with a drill, but that can easily be switched to a normal bore to accept a motor, as shown in the pictures/video.
