3:1 Planetary Gearbox
thingiverse
I designed three planetary gearsets so far, with this one being a 3:1 reduction, but I've created others with various ratios as well. All of my planetary sets are interchangeable and rely on a 0.500 inch or 12 mm hex as the input and output shaft. This means all of my gearboxes can be stacked to create different combinations. Each .stl file includes a sun gear, a ring gear, five planet gears, a carrier ring, and endcaps that enclose the gears securely. The holes in the corners allow for a number 8 or M4 bolt and nut to hold everything firmly together.
