Dive sticks
Designed in a single day, and they work exactly the way I wanted. Instead of buying a set, I made my own, and they stand perfectly upright on the pool floor in still water. The issue of staying down when knocked over into a certain position has been solved (in my testing I didn't see any persistance) with the introduction of the new cap.
Bill of materials (per stick)
1x M5x30mm bolt
6x standard M5 nuts
Assembly
Screw the M5x30 bolt into the base of the body.
Thread all 6 M5 nuts onto the bolt. An 8mm socket fits the nuts perfectly and makes this quick.
Tighten the nut stack down firmly against the base so the ballast sits as low as possible.
Snap the end cap onto the bottom to close it off.
Thread the top cap and assembeled bottom cap onto the body to finish
Optionally you can all glue it together for a stronger and safer final part
Print settings and printability
Printed at 0.2mm layer height in Prusament PETG Mango Yellow and PM Filament PETG Red. Every part prints without supports, but a brim is recomended for the body! Print the body standing upright and print all the caps flat on the bed. Please Don't Print it any Blue Filaments!
Material
I chose PETG for its chemical resistance to handle pool chlorine, though only long term use will tell whether it holds up fully. PETG is the minimum I would use here. ASA would be an even better choice for UV and chemical resistance if you have it. PLA is not suitable.
