Fish decompression release tool
thingiverse
This tool is used to release fish with expanded air bladder by sending them down to equalize pressure. A weight is attached to one side and a line to the other. Strong rubber bands should be used on the notches to keep it closed. Hook to the fishes lip and let the weight carry them down. pull string to release. Probably going to scale it up larger when i print to fit bigger fish. https://youtu.be/FDpeW2yCEbg
