We have 3D printed medium format and pinhole cameras. All of them are film cameras, we do not have digital ones.
Open source means that all the files for our cameras are available for everyone for free. It was always like this and will stay like this forever. My favorite part in this is that we improve the cameras together with the power of the community.
We encourage everyone to print and build your own camera, experience this journey, and feel free to improve them, redesign them or develop new functions, accessories, etc. If you would like to share your modifications with us and our community we are happy to upload your files as well to our folders.

It depends on the Helical adapter size you choose. We have 2 sizes available:
To choose the right model you have to know what is the focal length of your objective. Please make a careful reading on you particular lens and examine the sizes to determine which helical adapter fits your setup.
The front plate is available in 3 different diameter holes: 25mm, 28mm, 30mm. In case you need a unique front plate size, please send us an enquiry to info@doragoodman.com, and we can 3D print that for you for a specific lens.
You need a Mamiya RB67 Pro S back, or a Goodman 3D printed magazine.
The Mamiya RB67 Pro SD back won’t fit.
No, only the Pro S version fits.
Probably no, but we never tried that.

As it is a DIY project it is always possible that you will hurt yourself with a screwdriver for example. We suggest you to wear glowes and transparent glasses. And be extra careful. Don’t rush.
The Mamiya lenses fit exactly into the camera body, there is place for screws so you can fix it.
If you feel that it is too tight you need to sand very carefully the camera body. These cameras are printed one by one not on industrial machines, so there might be tiny little differences. We designed them to be more tight in order to avoid any light leak, so it can be always solved by sanding. The other way around would not work 🙂
It has Zone focusing, on all the Mamiya press lenses the necessary distance is marked, so with the help of that you can get nice, sharp photos. If you are not familiar with the Zone focusing it might worth checking some articles and videos about it before getting the camera as it is a special technique.
1. Every kit comes with a sports viewfinder, it is a small 3D printed part.
2. Every Mamiya press lens has its own original viewfinder that you can buy and attach to the camera.
3. We have our own viewfinding app, the GOODFINDER. Use it with your smartphone, its super useful! It is only available for IOS.
4. You can order our Goodman Ground Glass that you can attach to the back of the camera. Switching between the ground glass and the back is easy, fast and comfortable thanks to the small magnets the ground glass has.

This was made for the 35mm version, but you need to do the same steps in case of the 6×6 version.
Everything is included in the kit, even the screwdrivers, the sanding paper, etc. You just need time, a clean place, our tutorial videos and your patience.
As it is a DIY project it is always possible that you will hurt yourself with a screwdriver for example. We suggest you to wear glowes and transparent glasses. And be extra careful. Don’t rush. Safety first.

Its for removing strings of plastic that might be on the inside of the printed parts and to give a nice finish the outside of the camera. You should check the film route before assembly in the body of the camera and remove every small string carefully.
If you want a matt finish, then we recommend to sand every part individually before assembling it.
