3D-printable Motorized Wheel for optical filter turning

thingiverse

Often in optics laboratories, one needs to filter the light before analyzing it. It can be done by using commercially available optical filters. This project is a 3D-printed wheel, attached to a stepper motor, where optical filters can be placed at it. The motor can rotate the wheel, thus changing the filter which is in the optical path. Two pushbuttons, placed away from the wheel, for example, control the filter in-line.
