This is a Zoom Gear for use in Nauticam underwater housing that fits the Nikon 8-15mm fisheye zoom lens. It will work with both Nikon Z-Mount (mirrorless) and F-Mount (DSLR) cameras and housings. 

 

The design is made up of two printable parts. A rigid plastic gear made of PETG/PLA, etc and a soft rubber friction sleeve made of TPU. The TPU part slides over the zoom ring of the lens. (You do NOT need to remove the rubber grip from the lens which is sometime needed on similar gears) The Gear then slips over the TPU ring. It should grip firmly and not slide off or spin easily. If you find that it is too loose, use a strip of black rubber electrical tape around the outside of the TPU ring. That should shim it enough to make it snug.

 

Nauticam sells these Zoom Gears for over $250usd so this part can save you quite a bundle. This one works just a well for the cost of pennies.

Gear can be PLA or PETG, no need for more advanced materials.

Rubber Sleeve must be TPU 95. Print the TPU slowly at 30mm/s.

Great idea. I am planning a similar gear for a different lense ans uw-housing. How did you figure out the right gear dimensions? Cheers

Calipers! Take measurements, use the gear generator in Fusion360 or whatever cad software you prefer. The gear is effectively a template. The complexity comes in fitting it to the lens. If the lens telescopes, you need a muti-part design.
