32x8 RGB LED Matrix 3D Printed Diffuser Grid

3D printing a custom designed diffuser grid for a 32x8 RGB LED matrix display, which results in nice square pixels. The models for 3D printing are here: www.thingiverse.com/thing:1903744
The matrix has 256 WS2812 RGB LEDs (NeoPixels) on a flexible PCB and is being driven by a Raspberry Pi using Jeremy Garff's excellent rpi_ws281x library: github.com/jgarff/rpi_ws281x

What kind of plastic did you use to print the grille? The white petg is very translucent and the cells around the burning LED are illuminated...

Hey how i can get this thing what is cover the leds to squares ? Und how is it named ?

Hey James, how much $ would you (consider) charge for printing a 64 x 8? Like maybe a four piece panel?

Hi James. Amazing work. Can you tell me the dimensions of the each square and the width of each line which makes a square..

[@jamesward408]

Hi Saurabh, thanks! The squares are spaced on a regular 10mm square grid, their internal size is 9.2mm and the walls between each square are 0.8mm thick. Hope that explanation makes sense? Best regards, James.

Thanks James. That answers perfectly.

Which paper is used as the Diffuser?
Thanks.

[@jamesward408]

Hi Syed, I just used regular white paper, the LEDs are pretty bright. You could also try sanding some perspex sheet.

Thanks James. I also found others using stencil films. Cheers.
