Thanks to MakeChetti's remix. Why use bearings?
-Without bearings, the more belt tension, the more movement resistance.
-With bearings, you can tension as much as you want and there will be no movement resistance.
Tighter belts = more accuracy. Even I think this is an essential upgrade for your Ender 3!!!
0.2mm (case.stl can be higher)
