I wanted to move my spool holder from the top of the printer while keeping the filament sensor at the top.
So I found the object designed by hilleke (https://www.thingiverse.com/thing:3894537) but I found it too large.
So I remixed this one to remove the support of the filament detector because I preferred to use this one: https://www.thingiverse.com/thing:4006466.
I also manually tapped the inlet at the back to adapt a pneumatic connector to put a PTFE tube and connected it to this object: https://www.thingiverse.com/thing:3913591.
