Deep Sea Adventure (actually well thought out insert)

What changed: The original design only had correctly toleranced openings for the triangle and square pieces. I've expanded the other openings to properly fit all the other pieces. Newer versions of the game also seem to have wider player pieces, I've added an extra cutout to fit the last piece. The “insert_r1” version is what I've tested and shown in the picture. The “insert” version has the carry handle separated out as another piece so that it can be printed sideways (split in your slicer) and then superglued to the main piece for extra durability. Note that I have not checked that the tolerances are appropriate but a freecad/step file has been provided so it should be trivial to adjust.
