To make this project look nice and complete, I designed a backing to the RGB Matrix Panel that nicely houses the board and attaches to the back of the Matrix Panel. This was designed for the 64x32 RGB LED Matrix with 4mm Pitch.

Also, Adafruit switched over to carrying a 32x64 Matrix with a different set of mounting holes and there is a version of the design that has been updated to accommodate the newer matrix. So now there are four versions of the printable backing.

Single Piece for Newer Matrix

For larger volume printers such as the Creality CR-10 and Artillery Sidewinder X1, you can print the backing as a single piece. You can download the STL or 3MF files here:

Single Piece for Older Matrix

If you have the older matrix, you can still download the STL or 3MF files here:

Two Pieces for the Newer Matrix

Due to the size of the message panel, the design is also available as a 2-part print so that it can be printed on a standard 3D Printer.

This backing is designed to allow the entire project to be mounted onto a wall. The tabs hold it together well enough for mounting purposes. For mounting the Metro M4 WiFi, you will need these heat set inserts which it was designed for.

If you find yourself doing a lot of heat-set inserts, you could even build a heat-set insert jig by following our Heat Set Insert Rig guide.

3D Printer Settings

This model worked with printing using the following Slicer settings:

  • Use supports for the side with tabs if printing a 2-piece model
  • 10% Infill
  • 0.20mm Layer Height
