Creality filamentholder

Made this printable bolt for replacing the original creality spoolholder, this part is to replace the plastic part of the holder.

Also 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

I made a new nut, making the little shim on the picture obsolete.

Print the bolt with support.

20x42x12 is a cheap bearing i had easy access to, and also alot of hardware stores stock this bearing, that is why i chose that overkill dimension :-)

You will need two ball-bearings, one for each side.

Also made a adapter with no bearing option, but i strongly recommend using bearings.

I recommend printing the bolt with 5 outer walls, and fill at 100%, this bolt need to be strong.

There is also a extra long bolt here for 3Kg. rolls.

Feel free to comment, and give suggestions for improvements.
