Spool holder holder

thingiverse

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 centimiters 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. I also had to remove one of the protuberances on the ring in order to make it fit (see picture below), as a trade off for its stiffness. But you can sand them pretty easily. Also, it may seem that the spool can touch a very tall print, but a regular spool won't, since the nozzle can't reach that high. I've been using this part for nearly 8 months with the spool always hanging from it, and deformation is not visible yet.
