metaPixel is a simple, modular,  WS2812 LED-strip base LED panel. Each module contains 20 LEDs  in a 4x5 grid behind a 3d printed diffusor.  

The modules are connected by D-SUB high power connectors. Magnets on the sides of the modules add stability to the connection.

I have used black ABS for the boxes and clear [XT]( for the diffusor foil.

Autodesk Fusion archives and STEP files are included in the zip archive.

Materials and methods

For each module you will need:

- 1 x Diffusor + Grid either a full transparent (single piece) or glued together from grid and foil.
- 1 x Cover
- 1 x Box (there a 5 different versions differing in the position of the connectors)
- 3 x D-SUB,High Power Jack
- 3 x D-SUB [High Power plug](
- 4 x round magnets 3x3
- 4 x round magnets 4x3
- 3 to 6 x ring magnets 6/2,2
- 4 x [magnets 5x8](
- 20 x WS2812 LED from a 60LED/m strip.
- wires
- glue to fixate the magnets and to glue the translucent diffusor to the opaque grid (if used)

For the full display you'll need a sufficient 5V power supply and a custom programmed controller. A commercial controller will not work as expected because the LED layout changes with each metaPixel row (see CableLayout MetaPixel.pdf).
