Ender 3 universal spool support

thingiverse

Print spools with a width and bore up to 60mm in diameter that fit most standard systems. Simply run parts through the printing process, then repeatedly screw and unscrew the conical end nuts to clear the threads completely. Use the original nut to secure the support firmly to the metal bracket on your printer. Conical nuts print more smoothly from the bottom of the cone up to the top. It is essential that the tube is printed in a vertical orientation for best results.
