Spool holder for biger rolls.

This is my first design with 3D printing. I Bought an Flashforge Adventurer 3 and began looking for a good way to feed filament outside of the inbuilt spool holder that only fits smaler brand specific rolls.

This spool holder is amost friction less since i did build it on the idea of using two ball bearings as spool roller. The filament inner diameter is 53mm, so i bought two 620SRS ball bearings (25mm x 52mm x 15mm). Remember to remove the grease in the ball bearings and add a few drops of oil, and this will last forever.

At the picture attached i am using 1 kilogram (330 metre @ 1,75) roll.

This design was as i said my first design, so it is of course way more complex than it needs to be, with several elements made only for giving color variation/more parts.
