good idea, i will try that. Not sure the thread had enough flat surface on the edge that I can smooth with a fillet.

I actually used Fusion360 to model mine. the standard threads have the right size and fits, but I have no way to customize the shape of the thread tip and make it round.

wow, brilliant!

So how did you do that? 3D scanning? Your thread is definitely smoother than mine. I have sharp edges where yours are round and closer to the original design. Did you used one of the library threads or you created one from a custom vertical profile?

Nice job! It's very similar to my first iteration where I copied the surface air valve design with the handles. Then I realized, I actually don't need to move the part while diving and decided to make it low profile with the internal handle. I tried to copy the original design. I'll check the...

Interesting, so PLA is actually working for part exposed to water. I just "heard" that it's water sensitive, so that's the reason why I was considering PETG for the final part, but my PETG prints are less "clean" than my PLA prints. I would love to use PLA instead. You also mentioned "blind...

The plug will not have to maintain high pressure as the interior of the mask will be at the same pressure as exterior. It just needs to prevent air from escaping. I am more concerned if micro bubbles are trapped inside the piece as they will be at surface pressure and will shrink at pressure...

Cool, good to know. I also designed a BCD handle, I will try it next dive and post an update.

Yes the Oring is on the mask side, i am lucky :-) Just need to make sure the printed surface is very flat

I just finished the book "Dress For Success" by Dan MacKay. A lot of useful and comprehensive information. The book was written in 2011 and I think the chapter on lights may be outdated as it mentioned only HID and Halogen lights with canisters. With the recent developments of LED lights and...

Hi, I am scuba diver with around 100 dives, mostly trained in the south of France and CMAS 3* certified. I moved to the US (North California) 2 years ago and decided to go through a PADI training to learn a different way of diving. I am now PADI rescue diver certified. My point is not to compare...

Hi, I'm in the same situation and would like to build my own cable. How did you manage the connection between you circuit and the computer pins ? I can't find a plug that fits the computer pin... Thanks
