/diy/ - Do It Yourself

I have an arcade stick here, and there's this metal panel where the buttons push into, etc. I could try to replace it with a plexiglass or similar panel, but that's expensive, and there's not much room to fit it on there.

How would I go about applying a printed design that's durable enough to adhere to the metal and not get rubbed off by people's palms? Hopefully something that won't break the bank.
