<p>Simple Replacement for the stock filament cover to allow the attachment of a bowden tube</p><h3>Print instructions</h3><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><img class="image-style-align-left image_resized" style="width:31.03%;" src="https://media.prusaprinters.org/media/prints/2499/rich_content/e0e16e29-84ff-48e8-a90e-e14106fad435/unbenannt.png#%7B%22uuid%22%3A%22935e3141-101d-4d9d-961a-c8288da6e4a0%22%2C%22w%22%3A466%2C%22h%22%3A450%7D"><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> (PC4-01 Silver) should be what you need. It has the wide opening below, so that the tube can be passed through.</p><p><strong>Edit</strong>: thanks to the user samscowm for pointing out that the listing has changed. I am not entirely sure if the connector is the correct one. Maybe some user can confirm that this is the correct one, as i can not find mine anymore.</p><p>&nbsp;</p><p>&nbsp;</p><h3>Source files</h3><p>This was made from scratch in OnShape, here are the <a href="https://cad.onshape.com/documents/a9a9243c8ceb89deceb4575a/w/270e5b06c61dec4afd350ed4/e/10c0e65cea9a8d589896998b">source files.</a></p>
