6:1 Stackable Planetary Gear

thingiverse

Human: 15% fill on all parts except Sun Gear, Ring Gear, & Cover are filled at 100%. The Sun Gear is printed at 100% fill for strength and the Ring Gear & Cover should be printed at 100% (for strength) or 2mm Bottom/Top thickness to keep as flush and strong as possible. You need 1 of each file except for the Planetary Gear, which requires 3. The input is the sun gear (green) and the output is the carrier (red). It was designed so that a 5MM square will fit the sun gear snugly but not tight, while a 5.35 square hole will fit the carrier. The Ring gear may require cleanup afterwards if you end up with strings across the gears. A small file works wonders to clean up any binding while driving the sun gear and holding the casing. The gears are meant to be a very close but not binding fit. A handle was included to drive it, but anything else can be utilized as well. Updates will include a secondary gear hooked up to the sun to drive it via a worm gear with necessary attachments for it. Future updates will also include a way to lock the Ring Gear & Cover together so they won't rotate without manually holding them in place, and an add-on for a worm gear drive system for further gear reduction.
