12x12 matrix for WS2812B LEDs

A holder for WS2812B LED's. These can be folded up and placed into the holder so that they light up individual squares as pixels. I used two of these as a clock, but they should be able to serve as a general 12x12 display matrix. Easy to join together by gluing them onto a paper sheet. Instructions for putting together are at https://www.instructables.com/Arduino-WS2912B-LED-Clock/ This is a wholly new design but was inspired by The 'lazy grid clock' by Parallyze https://www.thingiverse.com/thing:4263318. The main inspiration is the way the LEDs are held facing sideways, but I did do a lot of work to get the design both to work well and print fast. The pixels were designed so that the whole thing prints with a minimum of retractions, which saves time and prevents stringing. See https://youtu.be/NONEyy7xZ_I and https://youtu.be/KTPxRiw5-so for a couple of clips of the clock in action
