Reverse Bowden System for Prusa MK3 - Redesigned filament sensor cover - Designed for enclosure

thingiverse

I wanted a reverse Bowden system for my enclosure as I now mount the spool holder on the side. This system works just as well for other use cases you'll find when searching for such a setup for your printer. 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. This design replaces the original "filament-sensor-cover.stl" by Prusa which can be found on GitHub. The most important part is that you need a Bowden tube coupler, which passes the tube through. (see pictures and parts section) My coupler was M10, and I had to screw it in with the help of a wrench. I recommend printing this in Black and PETG, though PLA should work too. The bowden connector you'll need is available at [this link](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&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&algo_expid=5beebc6b-abb1-498a-bf56-71eedb99c43d-0&algo_pvid=5beebc6b-abb1-498a-bf56-71eedb99c43d&transAbTest=ae803_3).
