G.A.M.E. elements

Printed elements needed for constructing a G.A.M.E. (a demonstrator tool for showing the working principle of a Scanning Tunnelling Microscope, STM). The scanner of a 3D printer (RepRap Berlin i3) is used as the scanner of the device. A crystalline surface made out of atoms (wooden balls) is imaged with a distance sensor attached to the STM tip. An electromagnet is also installed on the tip to manipulate a metallic ball representing an adatom.
The result can be seen at the following youtube links:
