Sub Cooler Keeper

I was tired of my subs getting soggy in the cooler so I designed a sub holder to keep it from getting water logged. I also drop this inside a gallon storage bag and it stays cold without worry of getting wet from the icy water while I'm fishing, on the boat, beach etc. Fits about an 8 in (3.15 cm) sub sandwich. I'll add a larger profile later to fit a footlong (4.75 cm). The threads need a bit of twisting to get them seated, but creates a tight fit. (obviously I know 3D printed materials
