Spur Gear Set, Module 1.0, 20 Degree Pressure Angle


These gears are to recognised industry standards for module system gears with an involute tooth profile.

Module 1.0 gears have a tooth spacing of approximately 3.1mm.

20 Degree Pressure Angle gives a tooth profile that is suitable for plastic.

These gears have been 3D printer tested, however it should be noted that producing of gears of this fine a pitch will be a challenging for some printers and software.

Presentation images are of the actual .STL files.

What You Get:

A total of 107 files!

STL files for ALL gears from 13 to 65 teeth inclusive.

There are two types of each, a 'plate' gear (a simple flat gear) and a 'boss' gear (a gear with a centre hub on one side.

The centre / pilot hole in each gear is 3mm.

Three types of rack are included, a plain rack, a rack with a flange on one side, a rack with a flange on both sides. The racks are each 50 teeth long.

Each gear has an embossed number of teeth on the side so you don't need to count teeth when you print them!


There are lots of gears available to print, but most are not to recognised standards, let alone a complete and useful set!


If you encounter any issues with these, please let me know! Creating these is highly repetitive and mistakes can happen! If you need gears with other teeth numbers, modules and pressure angles, let me know. More gear sets of different module to follow!
