I wrote the scad file by hand in OpenScad.
I designed this model so that I can create different size boxes to hold board game pieces. The inserts that come with most board games are often very inefficient, and don't allow room for expansions. So if you want to combine the game and all expansions in one box, you need to create your own insert. A customizable box that stays secure but is still easy to open is very valuable.
The author marked this model as their own original creation.
