A Fully Printable Microscope

Well almost, you still need to locate 4 lenses from some disposable cameras and a light source.

For the light source use an LED or mirror, whatever you have. I used a cheap LED wall light from Wal-Mart.

For the lenses, I went to a local photography shop and they were very kind to give me an entire bag full (Thank you Lens and Shutter! http://www.lensandshutter.com/). Since I had so many, I designed it to work with them all. There is a different optical tube that you have to print for the Fujifilm lenses (11.9mm outer diameter) vs. the Kodak lenses (13.2mm outer diameter). It should work with the following as I measured them all and will likely work with others as well:

(CAUTION there is a significant shock hazard if you plan to open a flash camera from the capacitor!)

Fujifilm QuickSnap Outdoor
Fujifilm QuickSnap Flash
Fujifilm Flash

Kodak FunSaver Flash
Kodak unaned
Kodak Max Outdoor

I will try to keep an updated list of potential online sources for these lenses and other components at Project.Parts:

The magnification of this microscope is expected be near 74x (still need to confirm precisely).
