Fazzstruder

So I got tired of grinding filament with the Gregs/Wades/etc extruder so I endeavored to create my own. The goal was to make a geared extruder with a larger diameter filament driver. The work of MoonCactus with his rollerstruder inspired this. I found later on that instead of the notches he cut into the head just cutting a groove and hobbing it seemed to work really well and was easier than trying to get the notches spaced properly.
This is designed for 3mm filament and I got good results
