Ender 3 - Bearing Spool Holder,The easiest

thingiverse

I designed an easy-to-make, filament spool bearing shaft. 2 printed, 1 8mm shaft (with length: spool width + washer thickness + nut width (height) for mounting), 2 bearings (8 x 22 x 7). The diameter of the spool is 53.5 mm on one side and 52.5 mm on the other, with a 5 mm deep 55 mm shoulder. Infill 20%, layer height 0.2 mm. Printing time ~2 hours If anyone needs help, write. I will be happy to redraw it to other sizes as well.
