A spool holder to fit multiple sizes of spools.
You will need 4 of 608 Ball Bearings to complete this Design.
4 M3 Bolts of length 25mm (Do not Exceed Dimensions Shown in Picture.)
4 M3 Hex Nuts
Added new design of the roller pins that won't require pausing the print so you can print all of them in a single print. Its designed with low clearance so they cannot be removed again easily. To fit, print 2 and slide them into the bearing 1 from each side, use a soft mallet and knock them in. (Just 1 swing did the trick for me)
