OpenSCAD Anycubic Photon M3 Z Limit Spacer

This is an OpenSCAD version of the original Anycubic M3 2.6 mm Offset for Wham Bam by meierme176. It allows you to vary the thickness of the spacer.

After I tried to install this on my Photon M3 it turns out that the original file can interfere with the linear bearing unless you are very careful. I have made changes to limit that potential on both of the files here.
