Filament Spool Holder for Ender 3

thingiverse

I decided to replace the stock coil holder for Ender 3 with a holder with bearings, for a smoother ride. I considered many options already existing and none of them suited me. I decided to make my own, simple, with a small number of details. There are only 4 printed parts, two bearings, 6 nuts and a stud. Also, if the diameter of the hole in the coil itself is different, you can change only two parts (those into which the bearings are pressed). Each bearing is preloaded with nuts on both sides in order to avoid turning its inner part on the stud (so that the bearing works). The only thing is, no matter how hard I tried and changed the printing settings and so on, the threads on the printed parts had to be modified with a nail file and lapped, but it's not too scary.
