3D printer filament Spool Support

thingiverse

I designed this simple thing to fit inside filament spools with an inner diameter around 53mm. It has one hole in the center too to fit the threaded rod from the Anet A8 filament holder. The outer diameter is 54mm and provides a nice tight fit. The diameter of the inner hole is 8.5mm. This print consumes very little filament, but is very strong and gets the job done. Print Settings Printer: Anet A8 Rafts: No Supports: No Resolution: .2mm Infill: 10% Notes: I used .2mm thickness, 10% infill, 80mm/s print speed, shell thickness of .4, bottom/top thickness of 0, 210c nozzle, and 50c print bed. Filament was PLA. Time to print around 7 minutes.
