Unfortunately the 3D-printer got damaged by someone, when i started to work. So i decided to work with materials that i can find in every hardware store. I made up my mind how the mechanism is supposed to work to adjust the camera‘s focus and how it can have a fixed stand. In class we developed the idea with the screw and the nut. I really liked that mechanism because it reminded me on the gluestick-mechanism. So i gave it a try. | |||

As you can see in my sketches, the difficulty i came up with, is about having a rotating wheel, that includes the nut and rotates in a fixed position, while pushing the screw upwards and with it the camera. My construction wants to have the rotating wheel setable from every hand-position so it is not thinkable to cover it from the top to the bottom part, because the covering would interfere with a smooth hand-movement. That means, the connection from top to bottom must proceed inside the whole construction. So i have two main-construction parts. Top-to-bottom-part (1st) and Rotate-and-Push-part (2nd). | As you can see in my sketches, the difficulty i came up with, is about having a rotating wheel, that includes the nut and rotates in a fixed position, while pushing the screw upwards and with it the camera.

The microscope is unfortunately not working that proper as i would like it to. The problem is that the free spaces are giving too much play. It is possible to adjust the focus of the camera, but not as smooth as i think it should be. | |||
Furthermore i wasnt aware that the sensor of the camera is very sensitive for friction and dust, so the quality of my image is full of noise. One should be really careful in turning and fixing the lense. | |||
