Always apply a plastic-safe lubricant, like or silicone oil , to your printed gears before running them under load. This massively reduces heat buildup and extends the lifespan of the plastic teeth. If you want to jump right into designing, let me know: What type of gear you need (Spur, Helical, Bevel, or Worm)? The application or project you are building? The dimensions or gear ratio you are aiming for?
Gear generators that export to STL format range from dedicated web apps like STLGears and Thingiverse to CAD-integrated solutions in Fusion 360 and FreeCAD, enabling precise control over tooth parameters. These tools allow users to define parameters such as module, pressure angle, and gear ratio for customized 3D printable designs.

Print at a higher temperature to fuse layers better, increase your wall count, or switch from PLA to PETG/Nylon. Orienting the gear flat on the print bed ensures maximum tooth strength. Post-Processing Tip Always apply a plastic-safe lubricant, like or silicone
