This is actually @James79 design, I take zero credit. I did upload it to Thingiverse today as someone was asking about it on FB.

@James79 if you'd like me to take it down so you can upload it, or take it down all together let me know. I gave you 100% credit it for it on Thingiverse.

I use this in my nitrox stick, works great!

Nitrox Stick Mixer_2" PVC by RobERob

Nitrox stick mixing insert. There are 2 files, they'll change the way the air spirals through to mix things up. I have this in a 2" PVC 24" long with a Solberg filter on top. Works great, very inexpensive solution, even cheaper than whiffle balls. I printed either 3 or 4 to fit in a 24" section...

Edit: Should also include the bushing / plug for the O2 sensor. The bushing fits inside of 1/2" PVC, so on my stick I have 2" x 2" x 1/2" T that this goes into to accept an O2 sensor. The plug is just in case you need to remove the sensor for whatever reason. The plug requires an o ring. Same one's that come on the adapter for the O2 sensor bung.

I might have cut the 1/2" down some do get the bung more into the flow, can't remember.

Nitrox Stick_O2 Sensor Bushing and Plug by RobERob

This is a bushing that fits into a 1/2" PVC fitting. It allows for the O2 sensor to be plugged into the nitrox stick. I used a 2" x 2" x 1/2" PVC fitting at the base of the nitrox stick. There's also a plug based on the same circumference as the O2 sensor in case there's a reason to remove the...

With these and some PVC just about anyone could build a nitrox stick for next to nothing. @tbone1004 suggested a solberg filter on top and that's what I have on mine.

Scaling change on James79's (James1979 on Thingiverse) BCD OPV. I scaled it to 50% for keeping the bulk off of a SMB --> DSMB.

Combining the Scuba bladder flange tool, scuba bladder flange (2 parts), and this BCD OPV I'm making a scaled down version for a SMB. This will make it a DSMB.

Because of hole scaling the inner bladder flange was too large for the outer bladder flange, and the outer bladder flange was too small for the OPV. The plunger was also a smidgen small. So this is my scaling in CURA: Inner bladder flange 50% in X, Y; outer bladder flange 51% in X,Y; Plunger 52% in X, Y; Tool 51% in X, Y; and OPV 50% in X, Y. I left Z at 100%. Now the threads and the tool mate perfectly.

I'm printing in PLA+, 0.4mm nozzle, layer 0.16, 220C to get good adhesion, and at 100% infill (probably doesn't matter with this file).

With any luck it will work in the ocean. I'll find out this weekend.

Hi

Just sharing my design for a OrcaTorch D630 GoPro mount.
OrcaTorch D630 Camera Mount by nickorossa

Printed in PTEG, it held up great at the weekend when I finally got to test it out.

DAAM/RAM/HPR parts and such by James1979

1st stage to body, and body to can gaskets are only a stopgap for when rubber and nylon ones are unavailable. Print in TPU, and the 1st stage gasket is very sensitive to over-torque. Mouthpiece plug is for the USD curved mouthpiece. Older (hardened) mouthpieces will still leak around the...

SP108/109 Seat Saver Key by James1979

Seat saver key for the SP 108/109/156. Designed in 2 parts for ease of printing. Insert the key through the center of the "S" disc on the regulator and turn 90 degrees to lock in place. keeps the lever depressed without deforming the purge cover.

A few more things I just got around to posting on thingiverse

DSMB mouthpiece adapter. I find I can't seal on the oral inflator in cold water, so I added a standard mouthpiece to mine. It has worked well for me for well over 5 years. A friend asked for one, so I got around to making new files. I have 2 versions. Use the one that fits your DSMB end the best.

DSMB oral inflator mouthpiece adapter by Raftingtigger

I have trouble sealing my mouth around the small oral inflator of my DSMB in cold water. I have solved this problem by making an adapter to use a standard scuba mouthpiece. I have been using this for about 5 years now and it works great. This is an updated version to fit a different DSMB end...

This mini dump valve did not pass the usage test.

V1 of a Goodman handle insert I made for the excellent XTAR D26 1600S. I paired it with the lower half of an Ammonite handle I had lying around, but part of V2 will be printing the lower half of the handle as well.

The other improvement I’d like to make is a surround/protector for the on/off button, as the electronic lock is fairly ineffectual and I’ve seen reports of people burning out the LED by having the light turn on during travel.

Printed with PETG with 100% infill, seems to hold up fairly well from its two saltwater dives so far. One of my first functional prints for underwater use, so any feedback very welcome!

Has anyone tried printing a mouthpiece?

I am looking for a drawing I can modify for my cyklon 300, has the extra large hole, I really like the longbite mouthpiece, and am wondering if some of the flexible 3d plastics would work....

 

[The Ruttmeister]

No, but using TPU with an FDM machine might work.

There are SLA resins that are suitable for prolonged skin contact but I'm not sure if any of those are flexible. Most SLA resins are pretty toxic, even when fully cured.

The gold standard would be a silicone, but I'm not aware of a good printer for silicone on the market. (There's one company making silicone printers, but it's not good or affordable).

I started trying to model one, but it kicked my butt. That was a couple years ago, though. With a decent design, the softest TPE you could print (for my machine it's duro 83) on a dual print head machine (different material for supports) would probably work ok. Other option is to print a mold and cast it in silicone.
