Here is Project Snowflake - A project completed with my Kids as a way to do some 3D printing, Electronics construction and Arduino programming of LED light sequences. Using the Awesome Adafruit Neopixel Libraries and almost any Arduino board.

The 3D Printed light sculpture is waterproof and can be used outside - hanging in a tree ideally.

Materials and methods

My Blog post here for further help and advice -

You will need to print 30 of the 3D Model segments, they fit together without the need for glue.

We used a Strip of waterproof WS2811 LED's from China - 50 are around $20US or less they are the 12mm type, and will snap-fit into the 3D printed modules.

A small Arduino board is also required.

Attached is a project file to get the LED's to dance. It's based on the Awesome adafruit Neopixel libraries and sample code.

A 12v or 5 v power supply of around 2 Amps (voltage depends on what type of LED's you order)

And do make sure to check out the essential Neopixel Uberguide on the adafruit website here -

Could not get a LED strip with enough distance between two LEDs.

Each piece printed perfectly.
Fantastic design Rich. I have also added a small box for the electronics and brackets to enable it to be suspended on an M8 threaded rod.

Hi SpikeUK, that looks really great. I'm pleased it came out well and all fitted.

The results were exactly as Rich said they would be. All sections fitted together perfectly with exactly the right amount of friction to force a very secure design. I have everything to complete the build, except for the LED string, which is on order from China.
