Parametric Epicyclic Gearbox Generator

thingiverse

A speedy parametric gearbox generator. Use a dedicated program to merge components if you want to print them all at once. This is NOT an in-place printing solution. I utilized ReplicatorG to shift all the models onto the print bed and flip the top cover plate, then Blender to combine all the models into one file for printing. Now tested, and minor corrections applied to the SCAD file. The included STL files are for the NEMA17 gearbox used in testing. It was discovered that it prints well with a 0.4 mm nozzle, but running the gearbox for a period of time with some Autosol chrome polish helps to ensure smooth operation. Once it's running more quietly, clean and grease before reassembly. Hardware required for generated models: three 3mm diameter, 18 mm shafts for the planet gears. M3/ ~20 mm screws are needed to attach them to the NEMA17 motor. Additionally, six washers - one above and one below each planet gear - help to separate them from the carrier.
