Spool holder for biger rolls.

thingiverse

I'm brand new to 3D printing and just got my hands on a Flashforge Adventurer 3. I needed a better way to feed filament outside of the built-in spool holder that's only compatible with smaller rolls from specific brands. This spool holder is almost frictionless since it was designed using two ball bearings as spool rollers. The filament inner diameter is 53mm, so I picked up two 620SRS ball bearings (25mm x 52mm x 15mm). Make sure to remove the grease and add a few drops of oil for optimal performance. In the attached picture, you'll see me using a 1-kilogram roll with 330 meters of filament at 1.75mm thickness. As this was my first design, it's naturally more complex than necessary, featuring multiple elements that add color variation and extra parts.
