<p>This is a belt extruder that I made for my dual extruder printer and has a 1:4 reduction and is filament sensor compatible.<br/> This extruder should be compatible with any printer and should be a direct fit in a any 20x20 extrusion profile.</p> <p>I shared the step files so you can modify the parts easily.</p> <p>Material list:<br/> 1x Nema17 stepper motor<br/> 1x Hobb-Goblin - 5mm ID Drive Gear<br/> 1x M5x40mm screw<br/> 1x Gt2_20T_6mm Pulley<br/> 1x Din557 nut<br/> 1x Filament sensor (<a href="https://www.amazon.com/Sunhokey-Filament-Detection-Detecting-Filament%EF%BC%88Pack/dp/B07N2GQHQT/ref=sr_1_5?dchild=1&amp;keywords=filament+sensor&amp;qid=1606337204&amp;sr=8-5">https://www.amazon.com/Sunhokey-Filament-Detection-Detecting-Filament%EF%BC%88Pack/dp/B07N2GQHQT/ref=sr_1_5?dchild=1&amp;keywords=filament+sensor&amp;qid=1606337204&amp;sr=8-5</a>)<br/> 1x 3x30mm screw<br/> 1x 200-2GT-6 belt<br/> 1x Pneumatic union M10<br/> 1x Extruder prusa spring<br/> 2x 688z bearing 1x 625z bearing</p> <p>Attention:<br/> 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.<br/> Don't tighten the belt to much so the printed pulley don't bend (this problem will be solved in the future updates).</p> <p>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.</p> <p>I would love if you shared fotos of my extruder in your printers.</p> <h3>Print instructions</h3><p>You need to use support in all parts, but you can print the extruder body without support in the fillament path.<br/> I advise the use of three perimenters and 20% grid infill.</p>
