FujiFilm QuickSnap Lens for Micro Four Thirds

Summary 

---

This is a 3D printable body for the plastic lens element from a FujiFilm QuickSnap disposable underwater camera. The Fuji website claims this to be a 32mm lens, which comes to 64mm equivalent on M4/3, from what I understand. I tried to replicate the f/10 aperture from the original camera as well. 

Parts Required

---

• 3 countersunk M3x6mm screws
• 1 lens element from the aforementioned camera 
• A printer and some filament

Print Settings

---

• Layer Height: I used 0.28mm, which makes for a near perfect fit with my camera, although I'm sure any other layer height would work just fine.
• Solid Infill
• Designed to print in the orientation provided in the files, which should be face down. The same applies for the aperture plates.
• Filament: I used black PLA, as we don't see super high temps here most of the time. If you're in a hotter climate something like PETG would probably do you better. I can't say how well it would print the overhangs on the flange, so you're on your own for that.

Assembly

---

1. Retrieve the lens from the Fuji camera (do at your own risk, although there are no electronics inside these underwater ones as they do not use a flash)
2. Print the model of your choice, either the larger standard one, or the universal one
3. Also print the aperture plate(s) of your choice
4. After printing:
   1.  Simply place the lens element into the printed body, making sure the convex round side is facing away from the sensor-side of the body
   2. Place aperture plate of your choice into the body, pressing the flat part of the aperture plate up against the back of the lens element
   3. While holding the aperture plate in place, screw the 3 countersunk screws in through the front and into the aperture plate until snug
5. Mount your new lens on your camera and enjoy!

After 6 revisions I have gotten the focus near enough to infinity for it to be usable in most situations you'd want to use this lens in, in my opinion. The model is completely free to use and edit to your liking if needed though, and I'd love to see any modifications. 

The result is a fairly hazy look, although that could be due to my lens element being scuffed and scratched a bit.

I have designed the lens body to fit specifically my Olympus PEN E-PL1, so I have also included a “Universal” version for cameras which don't have as much room to work with.

You are able to design custom aperture plates to get creative with the results, and I have included 4 by default. The standard circular aperture using the same dimensions as the original, a triangular aperture, a strange star, and 3 bars.

This is a fixed focus lens, although exploring a variable focus one in the future is not off the table.
