There are already a bunch of variations on these little insert rings/bushings but I wanted to make something parametric that I could easily regenerate for different brands. 

I only have access to a couple brands at the moment, so if you need a different diameter just drop me a comment with info and I'll add it to the list. The list below will also link you to the parametric settings for the source at Onshape:

  • Printed Solid
    • 58mm: Jessie PLA
    • 53mm: PS Imports (the inner wall on these spools is thicker, too)
  • Polymaker
    • 55mm: PolyTerra PLA, PolyLite PLA
  • OVV3D
    • 53mm: Identical to at least some of the PS Imports
