<h3>Extruder.</h3> <h3>Bondtech BMG style.</h3> <p><a href="http://bobblejot.com">Bobblejot Website</a><br/> <a href="https://github.com/Bobblejot/">Bobblejot GitHub</a><br/> <a href="https://twitter.com/bobblejot">Bobblejot Twitter</a><br/> <a href="https://www.patreon.com/join/bobblejot?">Bobblejot Patreon</a></p> <p>So i have decided to finish building my IDEX machine at the beginning of the new year and made the choice to use a direct drive Bondtech BMG and E3D V6 combo. My only issue was the Bondtech housing as i wanted something i could modify or mirror if need be.</p> <p>This led me to design a simpler version of the housing from scratch which would allow me to make any changes i needed. I also removed all the injection moulding features and cutouts just to keep it as simple and easy to print as possible.</p> <p>The body is slightly smaller than the original it was based off of, and the filament path is a bit tighter. The Inserted PTFE tube also goes further into the body on both sides.</p> <p>There are versions for various fittings. And all are available in both left and right handed versions.</p> <ul> <li>M12 press fit fittings</li> <li>M8 BMG press fit fittings. </li> <li>M6x1 threaded fittings </li> <li>M10x1 threaded fittings </li> <li>1/4" BSP threaded fittings. </li> <li><p>1/8" BSP threaded fittings.<br/> For the threaded versions i would print them at a lower layer height e.g. 160 micron or less.</p> <p>Designed for 1.75mm filament same as original.</p> <p>Extruder ESteps will need to be changed to 415.0</p> <p>Original extruder can be found here:</p> <p><a href="https://www.bondtech.se/en/product/bmg-extruder">Original Bondtech BMG</a></p> <p>Hopefully you may find it useful.</p> </li> </ul> <p><strong> Materials</strong></p> <p>I have provided Affiliate links to the items i used but you can get them anywhere you please.</p> <p>1 Off each of the below items :</p> <p><a href="http://s.click.aliexpress.com/e/cnZdVFZA">BMG Thumb Screw - Aliexpress</a><br/> <a href="http://s.click.aliexpress.com/e/bqonOxna">BMG Big Gear + Shaft - Aliexpress</a><br/> <a href="http://s.click.aliexpress.com/e/bGEkfzas">BMG Pinion Gear - Aliexpress</a><br/> <a href="http://s.click.aliexpress.com/e/vfY7aa2">M3 Square Nut - Aliexpress</a></p> <p>1 Off each fitting of your choice.</p> <p><a href="http://s.click.aliexpress.com/e/WsSTnU4">BMG Embedded Fitting - Aliexpress</a><br/> <a href="http://s.click.aliexpress.com/e/bY3tVDBS">12mm OD 4mm ID Push fit fitting - Aliexpress</a></p> <p>Or any other you prefer.</p> <p>2 off each of the below items :</p> <p><a href="http://s.click.aliexpress.com/e/cq4pYYBA">MR85ZZ ( W627-5 ) Bearings - Aliexpress</a><br/> <a href="http://s.click.aliexpress.com/e/byCGFdkM">Collet Clip - Aliexpress</a></p> <p>or</p> <p><a href="https://www.thingiverse.com/thing:2498383">My little printable clips</a></p> <p>For the Bondtech gears you have the Original gears from Bondtech which would be the preferred option.</p> <p><a href="https://www.bondtech.se/en/product/drivegear-kits/">Bondtech Original 1.75mm Gears</a></p> <p>But as always there are now clones available which may also work.</p> <p><a href="http://s.click.aliexpress.com/e/bW1TNKO8">Bondtech Clone 1.75mm Gears</a></p> <p>The choice is yours but it is always preferable to support the actual original designers and developers of a product.
