This is a magnet holder for your Scuba Octopus with a pipe diameter of 13mm. I have designed it to easy snap together and lock against rotation so it won't twist and lose magnetic force.
I have used simple round magnets with a size of 10x3 mm (In fact, mine are 2.7 high). If you need another size for magnets height or pipe diameter, let me know.
When assembling, make sure all magnets are pointing in the same direction. Push the magnets to the end, so they are centered. If you want you can use a soldering iron to slightly melt and push the plastics to ensure further fit. (That wasn't neccessary for me.) Finally, use two cable ties to fix the octopus part to the pipe.
Also, set 0.4 as the external parameter width so that the thin 0.8 wall that covers the magnets is stable enough. You don't need infill, but ake sure you have 3 or more outer perimeters. I used PETG because it seems rigid enough and hopefully won't lose any micro plastics in the water.
DISCLAIMER:
As you know, Scuba diving is dangerous. This part works for me, it might not work for you. When using, you agree that you do this on your own risk and will keep me free of any liabilty for any kind of harm that's caused to you or your
