Lockable pocket knife cover

This is a lockable cover for pocket knife, especially Suiss Army Knifes.
I have designed the cover, becaus in my contry there are more and more areas, where it is forbitten to carry a knife which is not in a locked box or cover.

The files in the atachement are for a Victorynox Suiss Champ. But there is a parametric moddel at Onshape, to change the dimensions of the cover with 3 variables, to fit ervery Suisse Army Knifes.
