Novelty Equation Key Tag

This was designed in response to thingiverse item 538098. The original item did not provide any design source files and instead provided only a single STL file. This STL file turned out to be difficult to edit. Since the original was available commercially this wasn't surprising.

However there are good reasons for wanting to be able to edit a design and one consisting entirely of text should be easy. This design provides a complete alternative and instructions for generating similar designs.
