Prusa Mini Filament Sensor Bowden Connector Adapter

<p>Hi all, I tried searching for an adapter such as this one but could not find anything like it.&nbsp;</p><p>I usually use my Mini for prototyping smaller parts and frequently use different color filament. I don't like to leave my filament out in the open where dust and debris can collect on the spool so I use a small enclosure for the filament. I have it sealed using pneumatic or “Bowden” style connectors and PTFE tube. I never liked having to push/pull the PTFE tube in and out of the filament sensor so I made an adapter to make things a lot simpler when loading/unloading filament.</p><p>I used a very short piece of PTFE tube, 9.44mm in length between the adapter and the sensor housing (see photo)&nbsp;that butts up to the connector threaded onto the adapter. I used a 2mm centering bit to give the PTFE piece an inside chamfer allowing the filament to guide smoothly.</p><p>I used a 4-40 X 22mm machine screw to secure the adapter onto the filament sensor. The connector has M6 threads. Total depth of the bowden thread in the adapter is about 5mm.</p><p>Working great so have fun. ;p</p>
