Superhero Toilet Signs

Since I first heard of the idea, that the female toilet-sign is actually a (Super)man with a cape, I wanted to make my own signs with Superman and Wonder Woman. I designed these pictograms a few years ago as vector graphics but back then I didn't have a 3D printer and forgot the files on my computer...

I printed them on a glass bed and they are so extremely light that they stick to my doors without glue, only by their own adhesion!

The background is only 0.3 mm thick, the blue parts are 0.
