Creality CR-10 parametric spool holder bushings/adapter

thingiverse

BEWARE: Before printing this part, measure the outside diameter of your printer's spool holder arm. Several people have printed this only to find out it doesn't fit their arm, as Creality used different metal stock in earlier printers. I've heard comments that this is designed for first-generation CR-10s. If you still want to print and don't have a caliper, save yourself from disappointment by printing just a few layers, stopping your print, and ensuring the part fits your spool holder arm. I couldn't find a suitable adapter or bushing for the stock arm on my Creality CR-10, so I created this one using Fusion 360. The threads are virtually play-free, with no size alterations for tolerance. It threaded easily without effort, even cleaning up fuzzies from my current PETG. The adapter runs along the length of the arm, holding large spools firmly in place while rotating smoothly. For smaller spools like those that come with the printer, I invert the female component and it fits perfectly. I might add a hex or wings in the near future to help remove the nut since it fits snugly on spools. If you print this and use it with spools larger than 60mm in diameter, but don't want to alter it, let me know for an update. If you print and use this adapter, please share your results, thank you!
