The Easy 35 pinhole camera can be printed in about 3.5 hours using black ABS or PLA, and needs only a pinhole (at a bare minimum) to complete and use as a 35mm camera. Pinhole cameras can take amazing photos if you take the time to slow down and think about the photo you are going to shoot!

After doing my “Pinhole Printed” Kickstarter project in 2013, I wanted to create a new 3D printed pinhole camera that anyone with access to a 3D printer can make. I’ve designed a number of 3D printed cameras, including the very popular Flyer 6x6 and Clipper 6x18 cameras which are now in the New Mexico History Museum and in the Poetics of Light exhibition running through January 10, 2016.

The Easy 35 camera satisfies my goals of fast, cheap, and easy to make. Based on 35mm film, the Easy 35 can be printed in half the time of a Flyer 6x6 and needs just a pinhole to assemble (at a bare minimum). A rubber band secures the top and black tape is used as the shutter. Such a camera appeals both to photographers and to educators wanting to teach principles of photography to youths. If you have a 3D printer, perhaps you can make some for a local school’s science class.

The Easy 35 body is printed as one piece, incorporating the film chambers, rails, internal light baffles, and pinhole mount. Such a camera body is only possible with a 3D printer, since it cannot be done in one piece with conventional manufacturing techniques.

The Easy 35 camera is released in the spirit of open source, using the Creative Commons CC-BY-SA 4.0 license, meaning anyone is free to make them or even sell them, as long as attribution is given to the designer and any remixes or derivations are shared alike.

Be sure to read the PDF on Making the Easy 35 before you start - it contains printing, assembly, and operating instructions. Details on the Easy 35 camera can be found on www.pinholeprinted.com, including where to find ready-made pinholes.

Bill of materials

  • 6 Printed parts -body, top, rewind knob, winder knob, 2 winder shafts
  • Pinhole (20mm disc with 0.20mm hole)
  • Wide rubber band
  • Black photo tape (for shutter)
    Optional but recommended:
  • O-ring (018 Buna-N 3/4” ID, 7/8” OD)
  • 2 screws (M3-0.5 X x 8mm pan head, #4 can be substituted)
  • 1/4-20 nut

(for the latest in documentation and sources, check pinholeprinted.com/support/easy35)

The body can be printed with or without a brim - the brim helps keep the body on the bed during printing. However, a brimless body file has been added so you can print without one or use your own slicer settings.

I think this is missing the top part of the model.

The top part is in the zip file. The body that you see is an alternate part without the brim.

Thanks! I will point out they were within a few .zip files, for me at least. I think I saw this originally and prematurely concluded the files "weren't there." Just pointing this out!

Thank you for this awesome camera! I printed my body and am really struggling to remove the internal film window using long nose pliers as specified by the pdf instructions. Anyone have tips on how to remove the filament in the window?

Is there any way I could bother you for the top piece without a brim? I can just fit the body sans brim on my M3D, and I'm hoping I can fit the top too.

I've added a body file without the brim - thank you for that suggestion! Sorry it caused problems for you.

Yes, as manugogli said, could we get a source file that isn't STL? The included "brim" in the file makes the camera too large to fit on my Printrbot Play. If that brim wasn't there, I could print it. Trying to edit the STL File but not having good luck. A source file (.3dm, Solidworks Part file, etc.) would be a LIFE SAVER. Thank you in advance!!

Does someone know where to find the editable Solidworks or rhino files?

why the "rewind knob" and the "winder" can't be one single part?

They are two different parts with opposing arrows to indicate the direction of winding, and to make it easy to remember which to use. Just print two of either knob if you prefer them to be the same and remember which is the rewind knob (the one the film canister is on) and which way to wind it.

I'm having slicing issue with CuraEngine unfortunately (Easy 35 B2 Winder)

Sorry to be slow in replying, I was at sea for 2 weeks. The winder needs to be sliced with Slic3r, Cura does not like thin walls for some reason and removes them. Cura works great for everything else.

For parts, including the pinhole (the only part absolutely required), check pinholeprinted.com/support/easy35 for the latest sources. The pinhole is available from eBay.

does this work, or is it just for decoration? If it does work, what else do I need to get to use it?

It really works, and you need a pinhole at the minimum (and film). If you'll read the PDF in the Thing Files, it'll tell you everything you need to know. The pinholes can be gotten from eBay - there's a link on my site at pinholeprinted.com/support/easy35 or if you're adventurous, you can make your own from foil and a needle, though results will not be predictable.
