In this guide you'll learn how to build a 3D printed Menorah that lights up with NeoPixel LEDs and CircuitPython. This minimalistic design features parts that snap fit together and print without any supports. The assembly is modular and easy to put together.

Light Up The Days

A push button allows you to light up a NeoPixel LED on each night of Hanukkah. The Shamash (center NeoPixel) stays lit each night. On the first night of Hanukkah, the NeoPixel LED on the far right is lit. Just press the button each night to light up the next one.

3D Printed Bulbs

The bulbs are printed in translucent PLA and the NeoPixels are fitted inside these little holders. The bulbs are hollow to better diffuse the LEDs so they’ll illuminate nicely.

USB-C Powered

The bottom has a cut out so you have access to the USB-C port. It can be powered by a 5V USB supply from either a computer or a wall outlet.

QT Py RP2040

This project is powered by the Adafruit QT Py RP2040 running CircuitPython. The QT Py is secured to the bottom cover and just snaps into the build-in holder.
