Very cool man....
My only thought is I would modify the design to get rid of those sharp sides and edges, unless your wrapping the label around the can.
Slip of the hand around those suckers and your headed to the hospital....
For protection you might even consider, getting you some lamination sheets, sandwiching the plate and running it through a hot laminator. They even make business card pocket, scale down the design to fit and it will seal the entire plate....no sharp edges....
