Belt Bowden Extruder w/filament sensor

thingiverse

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. You need to use support in all parts, but you can print the extruder body without support in the fillament path. I advise the use of three perimenters and 20% grid infill. Material list: 1x Nema17 stepper motor 1x Hobb-Goblin - 5mm ID Drive Gear 1x M5x40mm screw 1x Gt2_20T_6mm Pulley 1x Din557 nut 1x Filament sensor (https://www.amazon.com/Sunhokey-Filament-Detection-Detecting-Filament%EF%BC%88Pack/dp/B07N2GQHQT/ref=sr_1_5?dchild=1&keywords=filament+sensor&qid=1606337204&sr=8-5) 1x 3x30mm screw 1x 200-2GT-6 belt 1x Pneumatic union M10 1x Extruder prusa spring 2x 688z bearing 1x 625 bearing Attention: You will have to make a cut on the M5 screw to make the screw that locks the Grive Gear in place to not peek out of the Drive Gear, so that the Drive Gear can go inside the bearing. Don't tighten the belt to much so the printed pulley don't bend (this problem will be solved in the future updates). This is a work in project, 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.
