Box for Apex wetstones

I made this box for my Apex wet stones. OpenScad file has couple of parameters. There are two counts of wet stones since Diamant ones are slightly bigger. Slot width could be modified when you have thicker wet stones. The last parameter box Z is for the Z size of the whole box.
The box isn't symmetrical in the current edition, unfortunately. If you need two boxes to close wet stones for transport, you need to make a mirror version in a slicer.
