Convert the stock spool holder for the Artillery Sidewinder X2 from a roller style stand to a center spool mount.
This spool holder is a remix from https://www.thingiverse.com/thing:5031285
I designed it so that it replaces the stock rollers and has a 30mm hole for the spool holder itself so that you can use an existing spool holder design for the Ender3.

I have included the spool holder and stand files. The spool holder uses two 608-ZZ bearings.
UPDATE 4-27-23
I uploaded a v2 version that is thicker to support the weight of the spool as well is about 20cm taller to allow the spool to clear the edge of the metal stock spool holder.
