Hi, i just draw a bigger version of the original Gravity-Spoolholder-Nut so you can use filament spools like Sunlu with bigger holes up to 73mm.
My recommendation:
Print in PETG 0.15mm layer height, 15% infill gyroid, no support.
Standard:
Print in PETG or PLA 0.2mm layer height, 10% infill gyroid, no support.
The author remixed this model.
