Motor Mount Extruder

prusaprinters

<p>An extremely versatile direct-drive extruder for a nema 17 motor.</p> <p>It can be mounted as a bowden extruder (clamp included) or directly to a Wade-compatible or i3 x carriage.</p> <p>Uses m3 hardware for motor mounting and clamp, and can use either a 623 or 625 bearing - both versions are uploaded.</p> <p>Uses an mk7 drive gear, I got mine here: <a href="http://twelvepro.com/index.php?route=product/product&amp;path=61&amp;product_id=51">http://twelvepro.com/index.php?route=product/product&amp;path=61&amp;product\_id=51</a></p> <p>Allows full access to the idler teeth, even while printing - with tension adjust exposed as well.</p> <p>The clamps are meant for use on a Graber i3 printer - so they use 6-32 English hardware. I prefer to use the clamp to mount the extruder, rather than the extruder with the i3 mount built in.</p> <p>The bowden mounts are meant for use with the E3d hotend - their bowden tube pushfits have been drilled out, so the tube can pass all the way through - there is a hole for the tube to enter the extruder, and make sure that your filament is 100% guided.</p> <p>WHY another extruder?<br/> 1) it fits on a motor<br/> 2) it's modular - can adapt to wade or i3 mounts, bowden or wade<br/> 3) Minimal part count<br/> 4) Easy access to drive gear, you can even clean while printing!<br/> 5) Fully guided filament path<br/> 6) Super clamping power!<br/> 7) Tiny.</p> <h3> Instructions</h3> <p>Print WITHOUT support - all necessary supports are built-in with onionskin, and all cylinders are capped for easy printing.</p> <p>I usually use a .2mm height; the onionskin will work fine up to .3mm layer heights, but beyond that you might need to edit the scad.</p> <p>PARTS - needed for every version<br/> 3 6mm or 8mm m3 socket cap screws<br/> 1 20mm m3 screw<br/> 1 m3 nut</p> <p>PARTS - m3 idler<br/> 1 14mm m3 screw<br/> 1 m3 nut<br/> 1 623zz bearing</p> <p>Parts - m5 idler<br/> 1 14mm m5 screw<br/> 1 m5 nut<br/> 1 625zz bearing</p> <p>Parts - groovemount<br/> 2 6mm or 8mm m3 screws<br/> 2 m3 nuts</p> Category: 3D Printer Extruders
