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)
