Parametric open-source chopper wheel

thingiverse

A chopper wheel for optical and optoelectronic experiments, part of the Open-Source Optics Library, is designed by Michigan Tech's Open Sustainability Technology Research Group to lower the cost of scientific optical apparatuses. By utilizing OpenSCAD files, you can customize the wheel according to your requirements on an open-source 3D printer. Available STL files contain different slot numbers (4, 10, and 14) covering frequency ranges from low to approximately 1,400 Hz. Higher frequencies can be achieved as needed. The design includes code for wheels with a nut cage for secure mounting on spinning shafts. Further information can be found on Appropedia. Credit goes to Nick for the code. This component is one of several open-source hardware initiatives aiming to cut down the cost of scientific equipment. To learn more, follow this link.
