Universal Filament Spool Holder for M300

thingiverse

This replaces the OEM spool holder included with the Zortrax M300 printer, allowing you to use rolls meant for the M200 and M300 without needing to change the spool holder to a different size. It will also hold regular (non-Zortrax) spools. I've used it successfully to hold 2kg Zortrax rolls, the big ones, and it's incredibly strong. I printed it with a large circular base on the bottom, using supports and high infill, on my Creality CR-10 S5. The only place where supports are actually necessary is in the base where it clips to the machine. I printed at standard PLA settings with 0.2mm layers and it's super strong. Filament rolls glide more easily as they unwind. Give it a try!
