Deluxe sidewinder spool holder

Frustrated by the default spool holder and others I found I decided to design mine to overcome other design's issues.

This is the smoothest filament spool holder for Artillery Sidewinder X2 I've tested - it may work on other printers too.

You will need **4x 608ZZ** bearings (most commonly found) plus the metal rods and screws coming with the printer.

You need to print:

- 2x spool holder
- 4x spacer

Advantage of this design compared to others I found:

- adjustable tolerance by re-printing the spacers after adjusting the Z height (prints in a couple of minutes only, using little plastic)
- tight fit of the bearings (to glue needed, no wobble noise)
- no infill or support required
- no gluing of separate parts
- very little friction, unrolling of filament is butter smooth !
