QRD Skyline Diffusor

This is a Quadratic Residue Diffusor for creating a uniform, bi-dimensional scattering across a broadband frequency range (in this design, from 1.5kHz - 20kHz).

The dimensions of both the panel and the individual cells, as well as the cell heights are all dependant on the constraints of the frequency range you intend to scatter. Please refer to this calculator/Cell-layout if you wish to remix this project for your own use:

This project is listed in the Public Domain so please feel free to remix/adapt it for your own use. I highly reccomend using the aforementioned calculator if doing so, as it will help you determine the parameter changes you will need to enact. I am including the Fusion360 file, as well as the Diffuser in STL, 3MF, and OBJ formats.
