Very similar to previous design (<a rel="nofollow" target="_blank" href="https://www.youmagine.com/designs/nema23-direct-drive-extruder">https://www.youmagine.com/designs/nema23-direct-drive-extruder</a>) but after a good number of iterations and tweaks the design is much better now. I have been able to extrude ninjaflex through a bowden tube (as short as possible).<div><br> <div><br></div><div>I recently have switched to 4mm compression fittings for bowden tube attachment. This makes dealing with jams or stuck filament much easier and doesn't seem to fail like quick-connect fittings eventually do. </div><div><br></div><div><br></div><div>There are a variety of motor attachments. I have a custom one for each of my printers (SpiderBot, RoStockMAXX, and RoStockFAZZ) with NPT or M8 fittings for each.<br></div></div>
