Cosmic Frog + expansion insert

This is an insert for the Cosmic Frog boardgame, including the Finding Muck expansion.

The pictures show a prototype - the finished stl model files include some refinements: better slots to grab things, solid walls to space the tile trays, etc.

I did not want to make the Oomph tray bigger than needed, so it has 20mm empty space below/above it. I filled this with a bit of carton to keep everything snug.
