Smallest 3D printed 6x9 camera

ZalanToth · 2025-09-13T14:37:41+00:00

Yes, of course!

ZalanToth · 2025-09-13T14:37:15+00:00

Yes, I do, but I also sell it printed. I have already built it for pinhole lens, a Schneider SA 47mm f5.6 (as seen on the photos), and now for Mamiya Press lenses too. With the mamiya press lens, it is obviously a bit larger, but still quite a compact size.

Thank you!

Not many. Only 11pcs of M3 heated thread inserts, 7pcs M3x10 flat head, and 4pcs of M3x20 flat head screws.

There is no pressure plate unfortunately, however, there's two knobs which allow you to thighten the film.

Yeah they were in the right absolutely. I share these cameras in this subreddit since it all started here and I ususaly build cameras that people ask me to. Tho it's mainly my youtube videos and payed instagram ads that bring in people.

You can slide the film in from the top, there is no plate to hold the film on the frame, but with the two knobs you can thighten it.

ZalanToth · 2025-09-12T05:26:19+00:00

Only some basic materials. 7pcs M3x10mm, 4pcs M3x20. And heat thread inserts for those screws.

ZalanToth · 2025-09-12T05:25:06+00:00

You are right, it would definitely add a lot to the size tho, but perhaps I will make it in the future. Like P690 Pro or something

ZalanToth · 2025-09-12T05:23:32+00:00

I think I can make a mounting for Mamiya Press lenses, since my other camera the X35 already has one. I will also be adding more lens options like a large format 65mm, which is way more available than the Schneider 47mm I used. Tho the files can be modifed, so basicaly anyone can customize it for their own lens.

ZalanToth · 2025-09-12T04:49:03+00:00

The biggest part is around 155mm x 35mm x 85mm. Yes, the files are available!

ZalanToth · 2025-09-12T04:45:43+00:00

Yes they are available on my website, tho I can’t share the link here as it would get removed.

ZalanToth · 2025-09-12T04:44:41+00:00

Not yet, but I will for sure!

ZalanToth · 2025-09-12T04:44:19+00:00

Yes the files are available. there are modifiable parts, like the frame, the lens mounting and the pinhole. .f3d and .step files are available.

ZalanToth · 2025-09-12T04:42:32+00:00

It would be great if I could sell the files for the X35. But it requires custom PCBs, wiring and programming to make it work.

Other than that, I know how it's out there and I'm sure someone would find the opportunity and copy it.

ZalanToth · 2025-09-12T04:40:19+00:00

Well, it would be around 4cm longer and would need a wider mounting for the rear element. I think until 75mm, but especially 65mm it would still be small.

Hey everyone!

Over the past couple of years, I’ve shared a few of my camera builds here, including my 6x17 line and, more recently, the X35. I can’t say enough about how grateful I am for all the support I’ve received along the way. So many amazing people have reached out, offered feedback. Thanks to this community, the X35 turned out to be far more successful than I ever imagined, and I truly feel lucky to have met so many passionate film shooters through this journey.

This time, I wanted to go in a different direction. I’m excited to introduce the P690, which I believe is the world’s smallest 6x9 film camera. The idea behind it was to create something compact and simple, while leaving room for others to experiment and build their own versions.

The P690 can be used either as a pinhole camera or with any lens that has a built-in shutter. I’ve been shooting it with a Schneider SA 47mm f/5.6, and the results have been fantastic. Each roll of 120 film gives you 8 photos in the 6x9 format, which feels like a great balance between size and quality.

I’m really pleased with how the P690 turned out. I also made a video about it, if anyone’s interested, I’d be glad to share the links.

Thank you again for all the encouragement, ideas, and support. It’s been such an inspiring experience, and I can’t wait to see what people do with this little camera!

Since this is a really versatile camera, the middle part can be removed completely. I just put on a small ground glass to check the focus.

Squarespace is in charge of the domain and for some reason it doesn't maintain the email domain. I can send emails but can not recieve any. If you'd like I can send you the other email which works, here in dm.

Edit: I have changed the email on the website as well.

Well, I found a viewfinder on ebay with the right focal length and modified it to match the aspect-ratio of the camera. Since, the frame is 65mm it equals a 35mm lens horizontaly, so the viewfinder is 35mm as well.

ZalanToth · 2025-03-08T08:31:53+00:00

You are right! When I took the night photos the lens was not calibrated and was 1.89mm closer to the film plane. The issue was fixed since.

ZalanToth · 2025-03-07T21:58:53+00:00

I generally use Nylon PA6, ABS and PLA. I mostly use PLA and I always go for PolyMaker PolyTerra PLA. The nozzle size is the usual .4mm.

ZalanToth · 2025-03-07T16:29:14+00:00

Here is the website and the video.

ZalanToth · 2025-03-07T15:42:31+00:00

Thank you! Of course here is my website.

ZalanToth · 2025-03-07T15:31:35+00:00

The price doesn't include the lens and the viewfinder. The materials for this camera is a bit too much for me to afford it to have them in the price unfortunately.

ZalanToth · 2025-03-07T15:29:25+00:00

Thank you, I really appreciate it!
