This was inspired by https://www.thingiverse.com/thing:4625364.

I didn't like having to print it vertically, so I cut the font out rather than raising it to allow it to be printed flat. This allowed the corners to be filleted instead, and it prints faster and without support.

I also shortened the verbiage to YEP/NOPE, which is hopefully clear enough.
