Idler/Pulley Replacement with MR74ZZ ball bearings for Geeetech Prusa i3 X
thingiverse
This thing is too big for the x-axis, so the belt would grind the linear ball bearing of the extruder holder. So here's my second version of the replacement for the low-quality stock idler on the Geeetech Prusa i3. It has the same dimensions as the stock one and is used with four MR74ZZ ball bearings. Dimensions in mm: d1 = 11 (inner diameter) d2 = 14 (outer diameter) d3 = 7 (ball bearing diameter) I had to drill it a little bit with a seven-millimeter drill because it was too tight to push the bearings in.
