Spool holder holder

Thing designed to use instead of the spool holder holder (the metallic one) that Creality Ender 3 and Creality Ender 3 Pro printers provide. You will still need the tube and the ring. This can reduce around 8 centimeters of your printer's height!

I originally printed it with the big hole laying on the bed to keep it as accurate as possible, since the screw holes aren't that critical. I therefore had to use support for the "inside" (which was a pain to remove) and for the screw holes. You may want to print it with the screw wall laying down and support the big hole to make it simpler. It will depend on your printer's accuracy and your willing to sand it.
