16x16 LED Matrix (Cylinder Support Rings)

thingiverse

I made some support rings so that a 16x16 LED Matrix can be rolled up into a cylinder. This will hold the matrix in a cylinder that will keep its shape and LED spacing. The Matrix I used is the BTF-LIGHTING WS2812B RGB 5050SMD Individually Addressable Digital 16x16 256 Pixels 6.3in x 6.3in LED Matrix Flexible FPCB A small touch of glue is helpful in keeping the 'End Caps' in place. Another trick is to use a small black string to 'sinch' down the matrix to the rings while the glue dries. The string can be left on as it does not interfere with the LED's.
