Seas of Havoc Rock Atoll Sea Feature

I wanted a 3d printed Rock feature for the seas of havoc board game, so I modeled one by smooshing a bunch of other rock stls together. Its roughly in the ring shape that the standard cardboard token displays.
With these, it is better distinguished form the other sea features, since the others can be sailed onto whereas this one causes a collision when you sail onto it. Plus, with these printed, you can use the actual recommended count of sea features that the rulebook gives for 3 players.
