Hey :)

I designed a 3d printable grid. Its also possible to laser-cut it or to use a cnc.

Its for a DIY LED-Matrix with 16x16 WS2812B LEDs. The Idea is from Scott Marley.

You need to print:

17 x Rasterblatt-LED-Matrix-v4.stl 17 x Rasterblatt_mit_Nut-LED-Matrix-v4.stl

OR

17 x LED-MATRIX-GRID.stl 17 x LED-MATRIX-GRID-wStrip.stl

The difference is that the grid connection is a little looser with the second option. The thickness of the first option is 2.4mm and the diameter of the grid cut-outs is also 2.4mm. The second option is 2.4mm and 2.6mm. I recommend the 2nd option (LED-MATRIX-GRID)
