Geodesic LED Sphere

This is a design based on a geodesic sphere of either a 2V or 3V design.
It is designed to use WS2811 Pixels Digital Addressable LED String Lights which are readily available on Amazon, Ebay or Aliexpress.
These strips contain 50 LEDs.
You will need one strip for the 3V sphere which holds 42 LEDs, and 2 strips for the 3V model which holds 92 LEDs.

It uses 1/4 inch drip irrigation tubing. The tubing I used came from Home Depot.

Other brands may have a slightly different internal diameter. To ensure a proper fit you can modify the diameter of the led bushing arms in the openscad file.

It helps the heat the end of the tubing with a heat gun or hair dryer before installing on the LED bushing arms.
