Spool Holder/Roller with Print In Place Bearings

I tried to design a filament spool holder/roller that uses the least amount of filament.

It was printed using the standard Elegoo PLA 0.20 mm profile with the following modifications:

• Sparse infill pattern set to “Grid.”
• For the bearings:
  • Default line width set to 0.4 mm (all other line widths set to 0).
  • Wall printing order set to “Inner/Outer/Inner.”

Took inspiration from this video to design the bearings https://www.youtube.com/watch?v=kpoJ2Mhltbs
