Wade's Extruder Gears using Parametric Involute Bevel and Spur Gears

by Thingiverse
This is a set of gears for a Wade's Extruder The small gear is based on Nophead's grub screw version
I made these because I was having trouble slicing the old versions with RepSnapper (it can be very picky). These versions also allow changing the ratio or other features of the gear more easily as they are modeled in OpenSCAD.
I am using Vik's found here
