3D Printing

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. There are two versions of the printable backing.

Single Piece

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 file here:

Two Pieces

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. You can download the STL files here:

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.

We would also strongly recommend our heat-set insert soldering iron adapter.

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
• 10% Infill
• 0.20mm Layer Height
