Mount for Ender 3 spool holder

The Ender 3 V2 combined with the original spool holder tower did not fit in my IKEA STUVA enclosure. This custom mount enables the spool to be hung onto the inner wall of the enclosure.

It was designed so that the black cylinder that came with the printer can be pressed into the mount and then rotated to locked. For me, I only had to press it in to get a firm mount, so the original idea is there but not used. It holds 1kg filament firmly and feels very sturdy.
