About this 3D model

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!
