Deep Sea Adventure Board Game - Submarine Air Tracker

This is a replacement for the cardboard submarine that comes with the Deep Sea Adventure board game. It prints in two pieces which fit together in the center. A regular glass marble is used to serve as the air bubble/air remaining marker. There are 26 spaces around the ring. I've painted mine green-blue-yellow-orange-red in sets of 5 to make it easy to count the remaining air without having to write numbers. One space is left black to signify the last breath of air in the tanks.I printed the submarine at .08mm layer height and the outer ring at 0.2mm layer height. The sub was painted with a collection of craft acrylics and finished off with a high gloss clear coat to make it look wet.The diver models in the pictures are re-purposed astronaut figures I found (green army man style). I apologize that they are not available as STL files! I looked everywhere for a vintage deep sea diver model and had trouble finding one in a good pose for free.
