Inspired by http://boxmaker.rahulbotics.com/ got to code this openscad box modeler.
Ideal for Lasercut stencils, in case you want a simple case with box joints. In future, I may add dovetail option.
If you are as lazy as me, you will avoid going to AI to create those matching paths, instead code something that can reuse for different sizes depending on your need.
Modify your parameters on the openscad file.
-Choose top (with or without lid)
-in3D renders the box in 3D
-DXF, sets the dxf projection for you to cut your model
Choose thickness of your material on the top part and basic internal dimensions.
Use at your own risk, have to do some testing including tolerances etc...
