5DF Spool Adapter with 608 bearing - 3D Printed by Daniel Stinebaugh

Printed with a brim on my Anet A2 (that's not an option in the dropdown :P ) but probably not needed. I use these as calibration print's, and so I can reference what the end finish and color look like. After putting a bearing in this, I realized, some drag IS needed to keep the spool from self unwinding! So make sure that you are using grease packed bearings, abec-9's are NOT what you want here :) They are a great fit on both the bearing hole and outside diameter, if you feel it's a bit loose, turn the hub until it locks into the notched bends in the printed spool's the $5 roll's ship with, they are small, but they are there!
