Original thing was created in inches, and when I pulled measurements from the mesh, the dimensions for the Picatinny Rails were right on, but the inner sizes weren't right for standard North American 12 oz cans so I made some tweaks to the mesh. I haven't ran a test yet but it should go up to where the taper starts at the top of the can leaving the small top logos exposed for easy drink ID. Was then exported properly in mm.
