This script has been tested to created a 50mm cube from 7.5mm clear acrylic, here are the settings used.
Interestingly, the cube had an internal width of 42mm and external width of 57mm - this was due to the DPI, the generator assumes 100 DPI, the Inkscape default is 90 DPI. Once set correctly, it is highly accurate.

This is untested. May work well with wood but will not play nicely with the 7.5mm acrylic. burn baby burn the fun part

Help / issues
It's been found that if you try cutting with Acrylic underside's protective film removed, you will find 'swirl marks' after cutting. These are caused by the heat/smoke being extracted from the cut. To fix this, simply leave the protective film in place until you are finished cutting.
