LED Matrix with ws2812b to make Pixel Art, Sprites and Animations

thingiverse

These are DIY diffusers for creating your very own LED pixel display! This guide is tailored to a 12x12 matrix and requires cutting the main print into 9 sections to fit on my Ender 3. I know some folks use laser cutters or foam boards, but I found foam boards hard to work with, and I don't have a laser cutter! Video overview: https://youtu.be/TphJ3YlS4-I How to create: I cut ws2812b 30 led/meter into 12 led long strips and used the adhesive on the back of them to stick to a piece of plywood. Then I 3D printed the diffuser and glued them together with hot glue. After that, I wired all of the strips together and then glued the diffuser grid on top. Finally, I glued a black-led acrylic diffuser from Tap Plastics to cover it all.
