Ender 3 filament holder 608 ball bearing
Description
This is a filament spool holder for the Ender 3. I do think it will fit the other Ender 3's, but I am not sure, be sure to comment if you tried it on any other printer. The holder uses 4x 608 bearings. With this design the spool will unwind gradually. Other spool holders with bearings that i have used would unwind the spool to much, causing it to completely unwind. The holder slides on to the aluminum profile. You need to slide it in from the right side because otherwise you will hit the Z axis spindle. It is a snug fit on the extrusion so you don't really need to use the nuts that are used on the original spool holder. But I made the option to use it anyway. If you want to use it you need to remove the bolts of the top extrusion so the nut can slide in. If you have an extruder nob you need to remove it with high prints otherwise it will hit the spool holder in the printing process (because of the height of the print). I have used the spacer and bearing ring by Drykill_23. His filament guide works very well with this spool holder (I don't recommend using this holder without using a filament guide)
