This is a belt extruder that I made for my dual extruder printer and has a 1:4 reduction and is filament sensor compatible.This extruder should be compatible with any printer and should be a direct fit in a any 20x20 extrusion profile. I shared the step files so you can modify the parts easily.

This is a work in progress, so expect updates in the near future. I would like you to share, in the comments, your opinions and any problems you find. I would love if you shared fotos of my extruder in your printers.
