Salt and Pepper Grinder Base

Base(s) for salt and pepper grinders. Our grinders are approximately 60mm in diameter. I don't much care for OpenSCAD (or really know how to use it), so if you would like differently sized bases, let me know and I'll see what I can do. Alternatively, if someone was to create an OpenSCAD version of this, I would not object...

Side note, the two bases are joined by a dovetail-esque joint, which is fairly loose. Left it this way so they can be separated to be shaken / cleaned out occasionall
