Cardboard Filament Spool Adapter

Printed ring adapter for cardboard spools from Jessie's Filament. 

Quickly modeled this to stop issues with “Stuck Filament” error codes when the spool wasn't rolling freely.

It's a snug fit for my spools at 68mm outer diameter. 

Print 2 for each spool of filament.

PETG preferred for durability/smoothness.

Standard slicer/infill settings are fine. Input shaper is reccommended if you can use it.
