Ender 3 filament guide set for centered spool holder

thingiverse

Wanted to to fit my spool centered on top of the Ender 3 top bar for easy access. I am using various sizes of spools and made this remix both to have it angled correctly for the spool, but also to have a good guide for the top part and keep the filament neat. The two top pulleys hold the filament just tight enough that it will usually not loosen the filament on the spool when retracting. Uses 3x 608 bearings and go together with 3x 3mm nuts and bolts. The top bracket is designed to fit at the corner of the Ender 3, by unscrewing one of the two bolts and using it for extra fastening. To print a set you need: 3x rings 6x spacers 1x guide_lower 1x guide_upper To get the matching flexible spool holder look for flexible top mounted spool holder for ender 3 that I remixed. Note: If bearings does not fit well with the ring, get the other one from Holspeed's original listed as source.
