Trodat Printy 4922 Stamp Protection

I´m so important and so qualified ;-)
I´ve got a stamp from my boss, that I can not only sign a work I have completed, I can also stamp it with a Trodat Printy 4922.
Well, I work at different places and to protect the stamp from crushing or colouring my stuff while traveling I designed a litte case with a top.
First design with two little nails for the hinge and a little spacing.
This is a snug fit, you might want to print it at 102% size.
