Build neon-like signs using NeoPixel LEDs and 3D Printing! Use QT Py RP2040 and CircuitPython to make LED animations that bring them to life!

These strips feature flexible silicone diffusion for a neon look, with the individual addressable capabilities of NeoPixels. 

We 3D printed some signs that allow you to use the full meter long strip of NeoPixels.

It’s a simple easy press fit installation so there’s no need for cutting or splicing.

The four designs use a 1 meter strip to make simple shapes designed to fit on the bed of our 3D printer.
