This lens cover was designed for a projected in MSE 4777 at Michigan Tech. I imported Joshua Pearce's lens cover design (https://www.youmagine.com/designs/screen-cover) as a .stl file into FreeCAD. I then decorated the inside of the lens cover with the Chi Rho. This cover would hopefully block out more light in the thicker regions, so that the Chi Rho appears darker wherever the light is shining.
