CR-10 / Ender3 Ball Bearing Filament Support Spool Holder
thingiverse
I redesigned the excellent design by Greg191134, but it didn't fit my stock spool holder properly. It appears that some machines have different tubes, so I had to redraw it to suit my 32mm diameter tube. This modified design will now fit spools with a 54mm center. The four bearings used are 625ZZ, 5x16x5mm steel sealed shielded deep groove ball bearings. You can find them at https://goo.gl/N56PK5. I sanded the bearing holders to create a good push fit and also the pins that the bearings push onto. Check out the video showing assembly and other mods at https://youtu.be/uePhJEHGSmY.
