Parametric Snap-on Cover for Safety Razors

This is a simple snap-on design which doesn't take up extra space in a bag. It can be used with a blade installed, and it doesn't trap moisture. It needs to be accurately sized to fit your particular razor head.

I originally designed this a decade ago. This was one of the first things I wrote. It's not quite as neat as I'd like, but it works. Originally printed in PLA.

Two STL files (and parameters) are included for the following razors:

Merkur 15C/25C open comb razor

Gilette Superspeed (1960's flare-tip)

I doubt anyone will actually bother figuring out the measurements, but I figured I might as well throw it out there as a concept.
