thingiverse

This vibrant 3D printed decorative window panel pays tribute to the breathtaking beauty of rainbows and the enchanting properties of diffraction grating material. Diffraction grating is a versatile plastic sheet that mimics the behavior of a prism, skillfully separating the diverse wavelengths of light emitted from a brilliant white light source, such as the sun or extremely bright incandescent bulbs. Many people have hands-on experience with this fascinating phenomenon in elementary school science classes when exploring the physics of light transmission. For this project, diffraction grating is cleverly employed to create an intricate geometric sun-catcher that can be effortlessly hung in a window or on a shaded porch, adding a touch of mesmerizing elegance.
