A nice, easy to print, wall mounted bottle opener
Print it out, clean if necessary.
Insert penny (you may have to squish it in with pliers). The last version I printed out was a bit too tight so I made the hole a bit larger. Hopefully it isn't too large. I haven't printed it out yet.
Screw it to the wall (or whatever).
You'll want pretty secure screws since there's quite a bit of force trying to rip it off the wall.
