20x42x12 bearing shell, filament holder

Description

Made a bearing shell/cup for a 20x42x12 bearing, so that i can use it on the filament-holder, ensuring a smooth rollout of the industrial size core size on Form Futura 1kg. filaments 20x42x12 is a cheap bearing i had easy access to, that is why i chose that overkill dimension :-) You will need two ballbearings, one for each side. Edit: I have made a modified and better version of this adapter, witch can be found here https://www.thingiverse.com/thing:4345493 Feel free to comment, and give suggestions for improvements.
