I really wish OpenSCAD had objects, so you could use something like box1.width rather than having to declare variables for such things.

I tried using Build123d, a Python library that lets you use all of the features of Python. And it's supposed to allow specifically things like box1.width, but it's always 0. Lots of other issues/bugs too, and severely lacking in ddocumentation.Maybe it'll get there some day.
