This is an updated version of my old pizza bottle opener. It is now stronger and takes a coin after printing instead of halfway through, so it isn't so tricky to make.
Pepperoni slice with a keychain hole on the tip and logo on the crust.
Print without supports but cut away the little tab in the middle of the coin slot. Be sure to shove coin completely in, use pliers if needed. Works with a penny or dime depending on print quality / printer
