An alternative implementation of top z contact for Support material.

Is your feature request related to a problem? Please describe.

Overhanging parts that had support material on it, the dimensions perpendicular to it are off by the set z contact (which is bad for large twisty puzzles)

Describe the solution you'd like
Rather than the support material being lower than the part by the set z contact distance, attempt to have the part that is being supported be offset by the set z contact distance without having the part raised by the set z contact distance.

Describe how it would work
Ditto

Describe alternatives you've considered
Matt Bahner mentioned about compensating for this via cad but its really tedious and slow hence this feature request which would make it a lot easier
