About this 3D model
As none of the existing versions of this idler lever worked out for me, i created my own in Solid Edge. (Had problems with dimensions of holes.) Printed on my Artillery Sidewinder X1 at 0.16mm with 100% Infill. I strongly recommend using some type of PET-G or ABS as PLA would get soft from the heat at the hotend. Support is needed where the little wheel sits, otherwise no need for Support.
