WTB: Nauticam Extension Ring 20mm

[WTB: Nauticam Extension Ring 20mm]

Hi all,

I am looking to buy a Nauticam Extension Ring 20mm with Lock for my Nauticam A72 housing. I am based in Texas and happy to pay via PayPal. Alternatively, I am open to recommendations outside of buying new from retail. The model number is #21120

Thanks in advance,

Ross

Thanks for sharing Tim! Are you using a set screw in that design?

Thanks Wolf!

 

Did you print them on your own 3D printer or use a printing service?

 

Any advice on:

- designing the part based on my lens/housing (I have calipers and both in my possession)?

- getting the tooth curvature/size/count right?

- fitting the gear so it's "snug" but easy to assemble/disassemble?

[Looking for advice on 3D-printed zoom gears]

Hi all -

 

I am putting together a Nauticam rig (Sony A7Rii if it matters) and am enjoying (/sarc) the cost of the various components. While I am not looking to cut corners and risk flooding my camera, I have been trying to buy used components and save money where possible/reasonable. As part of my research, I am looking to get a manual focus gear for one of my lenses (specifically https://www.nauticam.com/products/sfe28-f-focus-gear-for-sony-fe-28mm-f2). I am a little shocked that a ring of plastic with gear teeth costs $175. I have seen some 3D models for zoom gears (https://www.thingiverse.com/thing:948608) and was curious if anyone had experimented with 3D parts.

 

Obviously, I wouldn't risk a part that needs to withstand pressure, but for something as simple as a zoom gear inside the housing under vacuum, this seems like a reasonable way to save over $100.

 

Thanks in advance
