Playing around in inkscape with an arbitrary 2D shape, the operation is
Playing around in OpenSCAD, for *some* shapes it may be sufficient to
- create a solid shape with the correct external surface
- multiply the dimensions by the relevant amount to create a slightly
- use the difference operator on the two shapes to leave a shell
Choosing an appropriate origin (if that's even possible) is obviously
