CR-10 Spool holder extension tube

thingiverse

This tube expands your stock Creality spool holder, allowing you to mount multiple spools at once. Printing in PLA is acceptable, but ABS produces better results. Place the internal screw on the bottom side and print with 5-10 brim lines. To create a modular support system, simply print additional tubes and connect them together. After printing, repeatedly screw and unscrew the screws to achieve proper adaptation.
