microscope iP4 holder / mount

Holder / mount designed keep iPhone 4 (in a case to make it simple and fast slide-in the phone) on a microscope (in my case on Levenhuk school microscope) ... still under development but works already just fine. The photos taken by iP4 are surprisingly usable and nice ... definitely incomparably better than from optional digital camera offered as accessory to this school microscope

EDIT: ... added revision 2 ... still as one object but improved eyepiece clamp + my recommendation to print it
