This is a spool holder for the creality ender 3 or 3 pro. It slides on, no threads needed. It utilizes two bearings so that there is less stress on the extruder motor.
- two bearings (see the pictures)- Two screws (optional, see picture)- The printed parts.
Note: I have optimized the bearing supports for shear by putting two screws through them, this is optional, and is only for being on the safe side.
Also note: this fits spools 75 mm wide
