Printable led matrix display. In the foot of the display there is a slot where a small circuit board can be fitted.

In the images the display shows the temperature in Celsius. The bottom two rows indicate fractional degrees, each led represents 1/16 th of a degree.

To do

• Create a circuit board small enough to fit nicely behind the display
• Build electronics to link multiple of those displays together.

Edit the open scad file to your likings. At the very least set number of rows and columns of leds you want to have.

Print the display. I used 0.2 mm layer height and 30% infill.

Populate with leds, and solder.
