Ender 3 Spool Holder (large), fitting as original replacement

thingiverse

A custom spool holder designed specifically for the original Ender 3 and Pro mount configurations. To assemble this fitting, you will require at least two M3 by 20 mm screws and nuts to secure both components together firmly. The printed spool holder and nut component can be easily integrated with the existing parts of your printer, making it a seamless drop-in replacement. This customized spool holder has an increased capacity compared to its original counterpart. While the original holder can accommodate spools up to 80 mm in diameter, this new model can hold spools as large as 150 mm in size, which is more than sufficient for two standard-sized filament spools. No supports are required during printing, except for the printed nut part, which needs minimal support to ensure it prints correctly.
