3D printable 49mm filter slip on adapter for 36mm lenses ex: Mamiya Six, Zeiss Super Ikonta

[Yobo57]

I made a 3D printable slip on adapter to fit 49mm filters on old folding cameras. The opening is 37mm, fits perfectly on my Mamiya six which has a 36mm wide lens.
Here is the link.
I would suggested printing with the smallest layer height you can, to ensure accurate 49mm threads.

Edit:
Alternate link

The link doesn't work for me, but then again I'm not super tech savvy.

Do you have a thread file? If you have a thread file, usually you can clean up damaged threads. That said, I know the threads on filters are quite small, but thread files used to be available for very fine metric threads 50 years ago when I bought an array of them for some very fine Swiss machinery.

The link should work, it’s a public google drive file. I could always send you the 3D object by email if you would like to print your own, just send me a pm.

Doesn't work for me either - it yields nothing more than a blank screen.

Link worked. Design looks very nice. I'm going to give it a go.

Link works fine for me. As to threads, my experiences trying to accurately print threads like these on a filament printer aren't very good. However, due to the softness of the material involved, I usually just use some protruding notches where the threads are supposed to be and then make the fitted part 'thread itself' in there.

I added a link to the google drive folder instead of direct to the file, let me know if that works

It might be easier to embed a 49mm filter ring or a 46-49mm step up ring to get a robust thread, rather than try to print it.

I have the file running on the printer at 0.1mm layer height at the moment out of curiosity. I have a camera this might fit, so it is worth it. Finding push on filters for the Zeiss is a bit hit or miss.

I certainly get more from that:

I'm guessing that those who are already working with stl files will normally have the viewer installed.

As I expected, my standard nozzle cannot manage threads that thin. A filter did snap in and screw out, as there are some incomplete lands. I have done coarser threads (M6) with some success.

This is pushing the limits of my FDM printer, though someone with a finer nozzle and more patience may get more consistent results. I am curious what the settings were for the original - material, temperature, speed, nozzle diameter, and layer height.

I printed mine in pla at 190 degrees, max speed 150mm/s with a layer height of 0.05mm. I used the anycubic kobra 2 printer, I believe the nozzle diameter is 0.4mm. The print is not perfect, but it gets the job done.

 

[grahamp]

My printer does not like layers less than 0.16 with a 0.4mm nozzle, but I see it might be worth some tests to see if I can get a better result.

I just had to join so I could say THANK YOU for this! Google led me here. @Yobo57 if I can successfully print this, this will be a godsend.

I have tried for years to easily adapt filters to the A36 slip-on style, for my Elmar 50mm… I came up with another solution for that (turns out the elmar has threads as well) but printing this and gluing in a step up ring would help replicate the functionality of the unnecessarily expensive SOOGZ adaptor. A much more elegant solution.

More recently I have been trying to get filters onto the Olympus lens on my Mamiya 6, which turns out uses the same A36 filters - and ONLY those slip on filters, as it is not threaded like the Leica Elmar, making this adaptor a more significant necessity.


I am a novice when it comes to 3D printing but I am going to see if my library can help out making a successful print. To my knowledge they have a Prusa printer available.

Is black PLA typically suitable for a photographic use like this that may be used outdoors in very bright sunlight?

No problem, I’m happy I could help! Black PLA should be perfectly fine, if they have matte black even better.

I haven’t used the filter on my Mamiya yet as I haven’t gotten around to repairing the bellows, but I used a similar 3d printed adapter on a yashica tlr and it worked perfectly. I also recently made an adapter to use a copal shutter on a bronica etrsi back using black pla and the results were light tight.

Let me know how the print works out for you!
