<h3>Background:</h3> <p>I wanted a reverse bowden system for my enclosure as I now mount the spool holder on the side.</p> <p>Works as well for the other use cases you will find when you are looking for such a system for your printer.</p> <p>The main reason I designed this was, that I was unhappy with the solutions I found and wanted something clean, fixed in place and sturdy, not some attachment.</p> <p>This design replaces the original "filament-sensor-cover.stl" by Prusa which can be found on github.</p> <p><strong>The most important part</strong> is that you need a bowden tube coupler, which passes the tube through. (see pictures and parts section)</p> <h3>Assembly</h3> <p>My coupler was M10, and must be screwed in with the help of a wrench.<br/> I recommend printing this in Black and PETG, though PLA should work too.</p> <h3>Parts:</h3> <p>edit after comment:<br/> <a href="https://www.aliexpress.com/item/3D-Printer-E3D-V6-J-head-Pneumatic-Connectors-PC4-01-1-75mm-PTFE-Tube-quick-coupler/32665289911.html?spm=2114.search0104.3.1.41094611acMaXI&amp;ws_ab_test=searchweb0_0,searchweb201602_2_10320_10065_10068_10547_319_317_10548_10696_453_10084_454_10083_433_10618_431_10304_10307_10820_10821_537_10302_536_10843_10059_10884_10887_100031_10319_321_322_10103,searchweb201603_6,ppcSwitch_0&amp;algo_expid=5beebc6b-abb1-498a-bf56-71eedb99c43d-0&amp;algo_pvid=5beebc6b-abb1-498a-bf56-71eedb99c43d&amp;transAbTest=ae803_3">This bowden connecter</a> should be what you need.
