16 X 16 LED Matrix Grids

The original is awesome, but the double thickness of two of them together was messing with my OCD, so I shaved off half a millimeter. Thanks to HTTP:\\www.thingiverse.com/makeitworktech for saving me an hour or two in Fusion. I added a thin diffuser on one model. To use this, print it front side down and switch from white to black a few layers into the grid by "pause at layer" and switching to black. Don't do it the first grid layer, or you may get black scraping snot lines onto the diffuser.
