Dungeon double doors

Double doors, double trouble! These double (2" wide) dungeon doors guard treasure, traps, and possible an orc with a pie.
The set contains three doors, and one nasty surprise. They can be printed without support.

The set contains:
- A skull door with three keyholes. This is where the BBEG waits for you!
- A key door, which probably guads a room with one of those three keys you need for the skull room.
- A mimic door! Whoops. What is your dex save again?
- A puzzle door, with rotating dials. Legally distinct from those other Nordic dragonslaying puzzle doors.
