Ender 3 spool holder with bearing
Description
Uses the existing metal bracket and adds spool holder with bearings. The bearings create a smoother pull into the extruder. It also has a printed nut to make changing spools easy without disassembling the bearings. You will need an 8mm threaded rod and 2 nuts. I also used washers but you probably don't need them. The only file that needs supports is SpoolSide.stl. Uses standard skate bearings (22 x 7 x 8)
