Things to make
Box generators

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.
Units | millimeters |
Width | 50 |
Height | 50 |
Depth | 50 |
Material Thickness | 6.5 |

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