This is intended to surround a sliding weight on a fishing line with a mount for a GoPro camera and a dive light if needed. This will let us see the structure when bottom fishing and hopefully record the strike.
I built this on my MK3S+ with default PrusaSlicer settings (no supports needed). The pictures show the fishing line threaded through the nose piece, then a 4oz sinker, then through the tail piece, and tied on a swivel. You then screw the nose and tail together to encompass the weight.
We will test this first without a leader to check for stability and balance. Then we'll go fishing.
