Ender 3 X-Axis Belt Leveler

Trying to solve the Ender 3 V1/V2 calibration inaccuracies due to the belt attachments making the lower ends of the belt not parallel. Since the inaccuracies are not linear, they will change with the position of the gantry while calibrating.

I designed a very simple belt shim to address this design flaw. I included the Step file, so anyone is welcome to improve it.

You have to print 2 of these, one as is with the bump on the right, and one MIRROR with the bump on the left.
