Developing a Useful retainer clip for a stowed second stage (octopus)

[drk5036]

So there has been a lot of discussion about how to stow a long hose for places that might require it. Myself, I'm using a 40" under-arm primary second stage, with a necklaced backup. For the meantime, I plan to switch my using my necklaced regulator during a dive, and would like to be able to clip off the longer hose to a chest D-ring, while having a breakaway feature for quick deployment if necessary.

In another thread, I saw someone linked to this clip: RAZOR Break Away Connector

And it occurred to me that this type of adapter is something that could easily be prepared with a 3D Printer.

The Basic Design goals are:
-a method to snap in a boltsnap, so the hose can be clipped to a d-ring
-a method to snap in a hose, so that it holds tightly enough that the hose stays in place, but
-can easily breakaway for deployment as necessary.

Does anyone want to give it a shot? I don't have a caliper to take the relevant measurements at the moment, but should have one get delivered soon, and then I can try to design something. @James79 do you think it would be easy to throw a design together?

Should be super easy to use that basic model you linked to, and recreate it. My only concern (that may be too strong of a word) is material choice. But ABS would probably be fine. I wouldn't use PLA, due to it's brittle-ness. Let me knock something together today, and see what happens!

First sketch;

I'll print one shortly for fit checks.

These are widely available and inexpensive ... though I just use bicycle tube around the mouthpiece.

Doesn't have a DIR friendly label though, so likely another 2 failure points

I completely agree.... but sometimes my fun is in Re-Inventing the wheel!

I use and I'm happy with snorkel keeper types like these:
2x Silicone Mouthpiece Holder Scuba 2nd Stage Regulator Octopus Strap Yellow | eBay

However that doesn't help the OP in his quest. Therefore, I went into my junk parts bin and pulled out a volunteer to send to anyone wanting to dissect/modify/destroy and turn it into the Six Million Dollar Man's octo holder.

An effective, reliable and widely accepted Octo clip !!!
Tis but a pipe dream.

Sometimes we just have accept that certain things are beyond the reach of mankind.

Even Elon Musk gave up on that folly!

Sure, show it to me after I reinvented it, lol
