Here are my 2D drawings and my sticker:

 

 

The game board design with possible features. I may add decorative etching on the raised edge of the box. I’m not sure at what depth I’ll place the grid, so that part doesn’t have a measurement yet.

The playmat design. This definitely seems more basic than the game board… so far.

 

The sticker design. Drawn manually with reference to a picture. While it’s printed out, I don’t have Scotch tape lying around, so it’ll stay on the sheet for a bit longer.
