Wide spool holder stock nuts

This is a replacement for the Stock spool holder arm of the Ender 3.
The stock one was just to narrow for some of the larger 1Kg spools.

The nice thing about this arm is that it is threaded to match the stock nuts that come with the Ender 3 spool holder. This reduces the amount of parts you will need to print to make this mod work.

I'm not sure if the stock arm just has a odd size of thread or if its just a poor injection mold. the nuts do fit the new arm they are just a tad tight the fi
