Here are the results of using it. This is about the same size (I think) as IC's version and is cut in 12.5 mm acrylic. I used 5 x 8mm magnets and pressed seated them with a hammer and a small block of Oak. Also the vacuum port is configured at 30 mm in my version (but you can adjust the variable to match a larger hose if desired).
The extra cuts visible in this are from an aborted attempt where I had mistakenly cut the magnet pockets from the outside of the pocket instead of the inside. I was able to flip the material and save the job with onlyh some minor cosmetic effects.
This is the assembled unit.
If you want to use the (attached) python script, you will need AnthonyB's lib found in the wiki (https://bitbucket.org/anthonyb/python-gcode/).
Hopefully it helps someone in a similar situation.
