Potential R1.2 Z axis carriage mount changes

[everycoloryouare]

There are two potential issues with the current z axis carriage mounts that could be changed for the R1.2 release.

1. The rear z carriage mount has the tension slot shallower than the front mounts. The moving tensioner was made longer and the front parts were changed accordingly, but the rear was not.

The rear mount should be lengthened to match the front, otherwise the tensioner sticks out quite a bit.
I realize that if the rear stationary tensioner was taller you could no longer get the screw in for the bearing. Maybe there is no elegant solution for this.

2. The new counterbored holes on the front carriage mount have very thin geometry near the outter edge. This causes very thin webbing when printed which breaks off easily. The webbing could be removed and chamfered vertically to blend into the top and bottom.
