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: https://project.parts/project/77450/

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

This project was also inspired by this excellent project: http://www.funsci.com/fun3_en/ucomp1/ucomp1.htm
and this: http://www.thingiverse.com/thing:31632

This should work with a variety of printers and settings. I printed it on a Makerbot Rep 2 using black, silver, and white PLA. For the optical tube, rack, knobs, pinion, stage, and head I used 0.1mm, 15% fill and high setting. For the post and stand I used medium settings, 0.27mm, 2.5% fill. It should have enough tolerance for medium settings everywhere.

Looking forward to your feedback on the build.
