Someone on the O2ptima rebreather group made this awesome tool for opening the DiveCan canisters on our rebreathers. They can be hard to grip when wet.

He shared the file with the group. I don't have a printer, so I asked my friend Nathan if he would print it for me.
This is what I received. It is functional, but not exactly the same.

That's such a great joke. It's 5:15am here and that had me laugh out loud.
