Magnetic Filament Pass for Ikea Lack

prusaprinters

<p>This is a magnetic filament pass and matching PTFE connector for an Ikea lack enclosure. It allows the user to quickly swap between filaments from different dry boxes while not restricting the user to print only out of a dry box. The pass is PTFE lined to prevent wear and reduce friction. To install drill a 10mm hole in the desired location, put the pass through, and use the printed nut to secure it. The PTFE connecter slides onto the end of your PTFE tube. I designed the PTFE tube to be press-fitted however the magnets may need a little superglue if they are loose. I used 15mm x 4mm magnets because that is what I had on hand but I plan to make another version that uses smaller magnets when I can. For now, you can find the ones I used in the link below. I have also provided the f3d files and STEP files if you wish to modify them.&nbsp;</p><p>&nbsp;</p><p>Magnets:&nbsp;</p><p><a href="https://www.amazon.com/ZDYWY-Countersunk-Permanent-Refrigerator-Neodymium/dp/B096B793MY">15mm x 4mm x 4mm hole</a></p><p><a href="https://www.amazon.com/dp/B09XK5GN3M/?coliid=I1BKBJGUNE5GZG&amp;colid=2CRSO5YR9BWJY&amp;psc=1&amp;ref_=lv_ov_lig_dp_it">12mm x 3mm x 4mm hole</a></p><p>&nbsp;</p><p>Updates:</p><ul><li>Added pass and connecter for 12mm x 3mm countersunk magnets&nbsp;</li></ul><p>&nbsp;</p><p>Future plans:</p><ul><li>add different magnet sizes</li><li>add a magnetic “dock” for dry boxes</li></ul><p>&nbsp;</p><p>Print:</p><ul><li>0.2 layer hight</li><li>15% or 20% infill</li><li>3 walls</li><li>supports on (for the part the magnet fits in)</li></ul>
