A tile for hextraction!

Rules: on play, remove the key from the back of the tile and add it to your Inventory.* While the key is in your inventory, on your turn you may lock or unlock the tile before or after rolling.

* Inventory is a new term I've come up with to mean "accessories to tiles that you keep alongside your hand." Effects etc. can interact with the inventory.

Print one of every part, connect everything with three M3 screws.
