Parametric container with threaded lid (OpenSCAD)

There are quite a few parametric containers on here, but most of them are done in Fusion and I wanted to make one in OpenSCAD. It pretty much relies on the Belfry OpenSCAD library, so you'll need to install it in order to render new variants of the file.

A few key points:

- FDM-friendly threads
- option to make the container bottom chamfered or rounded
- optional text on top cap, bottom or container wall
- pretty darn configurable
