60/11 Drive gears for Adrian's NEMA17 Geared extruder

This is my revised set of gears for Adrian's NEMA17 geared extruder.

This is a gear profile I use when I design gears for paper shredders, the gear profile meshes smooth and without play between the gears.

The drive gear uses a 1/4" shaft.

Two 60 tooth gears files are posted,Rev1 can be printed without a support material Rev2 is for printing on a machine with support material.

Enjoy!
