I finally was able to borrow an n100 extension ring to get measurements and make prototypes of Nauticam n100 compatible parts. I can print out any size ring from 20mm on up.

It all fits perfectly, but still needs to be tested in a vacuum sealed housing followed by a test dive. The basic design pattern and pressure resistance is well tested in the n120 versions I've been using for months.

The person I borrowed the ring from is out of town for a few weeks, and I don't have a housing to test it,

I need to find someone else to test it out. Any volunteers??

If you want to send it to me, I can easily test it to the 100m that the Nauticam stuff is rated to.

That is very generous! I will take you up on the offer, perhaps with two or three items if it's not too much trouble. An n100 and n120 extension ring. Ideally these can survive 100m.

And perhaps a float? Like my HF-1 strobe float. I would be happy if that survived to 40 meters. I have dove these a bit over 30 meters. They are not as thick as the rings and ports, but they are no loss should they fail as well.

I will message you for details.

Cheers,

Dave

@Dave_Hicks Sure, no problem. Though my 100m chamber has an inner diameter of only a little over 100mm. It can fit N100 stuff but not N120. My larger chamber can fit N120 stuff and even housings, but it maxes out around 55m.

That sounds great. 55m is more than enough for me. Do you have some end caps to seal the ends of n100 / n120 rings? Or should I provide something?

Cool. Yes I do have waterproof caps for sealing both ends of the extensions.

I have access to a chamber which can do 100m, but it's in Victoria BC.

Hi everyone, dear Dave,

I am new to 3D printing, but I have access to freshwater diving here at home and can take any housing down to 40 m. If you would like, I can give it a try.

I may also be able to print the part, provided it can be printed on a Bambu A1 Mini. However, I do not have an enclosure for the printer, so I am not sure whether a more advanced setup would be required to achieve the desired level of quality.

Warm regards

Selim
