Overly complicated reel holder for the Ender 3 using skateboard/608zz bearings.

I noticed after using my Ender 3 for a bit that the spindle was getting worn down and greyish dust was coming off of it, so I designed my own.

You'll need 6 x 608ZZ bearings, the quality of them doesn't really matter that much, they don't take a lot of force in this application so any old cheap ones will do.

It should fit reels with a hole size of 54mm to 78mm, included are some spacers if you have a really thin reel. It should be pretty trivial making up an adapter if you have a really wacky reel size.

Everything pushes together, with the exception of the 4 nuts to hold it all together. It fits in the same hole as the original Ender 3 reel spindle.
