Filament holder for ender 5 (plus) - Centred bearings

thingiverse

Filament holder This filament holder is designed because I wanted a filament holder where the bearings are put on the rotation axis and where multiple sizes of spools would fit on. It runs really smoothly and keeps the spools rotation axis perfectly in the middle of the bearings. The holder uses a cylinder consisting of two identical parts where two z608 bearings are fitted in to (outer diameter 22 mm, inner diameter 8mm, thickness 7mm. In the cylinder there is place for three spring loaded fingers that can move from a diameter of 49 mm to 62 mm. It uses two bed levelling springs (length 20 mm, diameter 8 mm) per finger, other springs probably also work but I found these work quite nicely. I used a 8 mm thick wooden rod as an axis which is pushed into the bearings and into the locking cap. The locking cap uses the same system as the original spool holder so the ring can be re used to lock the cap onto the metal arm. Because of the bearings there is now way to hold the locking cap in place while tightening the ring thus a hole is added where a hex key or other object can be put to hold the locking cap in place. On the other end a small cap can be placed to enclose the entire system. The holder now uses three fingers this amount together with the strength of the springs makes a tad difficult to load spools so when I have time I will make a new version and test it. So i wouldn't recommend this system with the current springs, if you have better suited springs by all means use it but for now i just wanted to share the first version. I hope you like it!
