Gearbox

thingiverse

A compact 1:4 gearbox perfect for enthusiasts or instructional purposes, featuring an easily accessible lid that demands caution from curious digits. Attached is a precise coupling designed specifically for a 2.3mm motor shaft, sliding effortlessly onto the gearbox's input shafts. To print this design efficiently, consider adding supports only to the larger gear while printing the remainder without them. Below are step-by-step assembly instructions: You will require two M6 self-tapping screws, approximately 10mm in length, which should fit snugly into place. A light coating of lubricant on the gears and shafts ensures smooth operation, eliminating unwanted squeaks. When running at high speeds above 4000 rpm, be sure to keep your fingers out of harm's way.
