Simple lidded box

Simple lidded box. Configurable with rounded corners and rims. See OpenSCAD file for details.

There is only one file, which you use to create the box as well as the lid. Let x, y, r(adius) and w(all width) have the same values when you build the lid for your box. For the box, set outer rim to 0: for the lid, set inner rim to 0.
