Behold the improved housing and ball joint for the filament feeder / indicator for the Elegoo Centauri Carbon! 

This design features 4 variations accommodating Elegoo's Batch 1 & Batch 3 designs for the filament feeder mounting, as well as accommodations for 2 different Bowden tube couplings sized for either the PC4-M6 or the PC4-M10 pneumatic connector fittings/couplings for PTFE tubes.  

The model is designed to have a ball joint that can allow the filament feeder to reach a multitude of angles in all 3-dimensions so that it can be oriented to smoothly run filament from your desired filament reel storage without bending or snagging the filament! You wont need to move your printer and filament storage containers around anymore, just print and enjoy the customized freedom your setup deserves!

The rods for the circuit/gearbox are small and as with the nature of 3D printing, they can break, so be careful when installing your parts. The bearing should be seated at the right height naturally, but may very depending on the moisture, swelling, and warping of your desired filament during printing. If the filament isn't feeding smoothly through the box, then this is where the issue lies. The groove in the bearing needs to line up perfectly to create the open channel for the filament.
