The 3d Printing Scuba Page

This page contains interesting and fun DIY novelty projects for scuba divers who also own or have access to a 3d printer. Many of these are projects we've made for fun over the years. In the spirit of fun and sharing in the 3d printing community  we've decided to make these projects public for those who wish to attempt them. 

These projects and associated instructions assume you own a FDM 3d printer, or have access to one, and that you are skilled in using it. These pages are not meant to be a tutorial in 3d printing. these projects were made using a Prusa I3 mk3s FDM printer, using a Lack enclosure and ABS filament for most projects. 

There are many different printers and each has their own nuances, which unfortunately we cannot offer assistance in. It is very important to have your settings correct. Live-z height, temperature, extrusion rates, should all be dialed in for smooth and accurate prints. 

 

Do you not have a 3d printer? There are also commercial printing services available that can print these projects for you if you are so inclined.

Difficulty: Easy

For our dive boats, we need to refill the shower water using old 5-gallon containers of rebreather absorbent. 

Pouring the water out of them into the freshwater deck fills was a tedious process of pouring while balancing funnels. This was designed to make the process of pouring liquids from sorb canisters easy. 

It's a very easy print, and requires minimal assembly of a 7/8 hose and hose clamp. 

Difficulty: Easy

This is a simple funnel that screws on to the top of a Molecular Products Sofnolime canister. It allows you to pour unused sorb (or anything else really) back into a keg.

 

Yes, you can 100% do the same thing with a $5 funnel you can buy anywhere. But this is a fun and simple project for someone new to 3d Printing to cut their teeth with. Single piece print with no assembly required. 

Difficulty: Easy

A simple funnel that can be screwed on to a Molecular Products Sofnolime canister, allowing for easier pouring.

 

Single piece print with no assembly or support material required.  

Difficulty: Intermediate - assembly required

for rebreather divers. This is an iris-style valve assembly for your CO2 absorbent container, which allows you to mount your absorbent keg upside down, and pour the sorb into your sorb cassette with the flick of a switch. 

This was originally made as a novelty gag, but it actually works and is very convenient for rebreather divers. 

This is a simple print, but requires some involved assembly using 14 M3 hex head screws and nuts. 

Difficulty: Easy

For underwater photographers using a Canon 100 2.8 USM Macro lens, this gear can easily be printed. For use with Nauticam Housings. 

This is a simple, one-piece print, but does require an M3 hex head bolt and nut to secure the gear to the lens. 

Difficulty: Easy

For underwater photographers using the Tokina 10-17 Fisheye lens in a Nuaticam Housing, this gear is simple and easy to make. 

This is a simple, one-piece print, but does require an M3 hex head bolt and nut to secure the gear to the lens. 

Difficulty: Intermediate - thin print with support material

For underwater photographers using Inon Z330 strobes, this is a simple method to apply a color shifted diffuser for some unique effects. 

This is a simple, one piece print using minimal support material.

The $10 snoots for Z330 

Difficulty: Intermediate - Assembly and finishing required

This is a fiber optic snoot for Inon Z330 strobes. It allows you to focus your strobe light to a tiny little spot - perfect for tiny macro critters. Commercially made snoots of a similar design are listed online for $300 each. This is what my British friends would call "Taking the piss." This identical snoot can be made for as little as $10. 

 

You need to source a length of fiber optic cable, some Loc Line parts, and epoxy. Easy to print and require some minimal assembly.

The $20 Nitrox Analyzer

Difficulty: Hard - Requires careful assembly, knowledge of soldering, electronics assembly, Arduino programming, troubleshooting

This is an Arduino based nitrox analyzer that uses your old rebreather oxygen sensors. After a year, a rebreather o2 sensor should not be used at PO2's above 1.0 in a rebreather, but it's perfectly fine for a year's use in an oxygen analyzer. 

This is a pretty complex project. Not for the faint of heart. 

File coming soon

Difficulty: Easy 

Adds 640 grams of floatation to the Nauticam EMWL relay lens section. 2 halves bolt together with M3 x 12mm hex head bolts. 

Difficulty: Easy 

Adds about 230 grams of floatation to the Nauticam EMWL relay lens section. 2 halves bolt together with M3 x 12mm hex head bolts.
