Sharpening Stone Holder

I do a bit of knife sharpening at home and have this sharpening system:

I bought some good quality stones to use with the system and wanted a way to store them where I could keep them from getting damaged and know which grit is which (especially when the lettering wears off). I made some little slots where a label can be placed. Here is an example of one of the stones:

This, as well as all of my designs, was done in inches. If the size looks super small in your slicing software, multiply the scale by 25.4 Let me know what you think and post those makes.

Enjoy!
