My wife says that I don't have Christmas spirit, so I decided to do Christmas how I wanted to do Christmas! I remixed it, and learned some things along the way. This Christmas tree allows you to insert three NeoPixel Ring 12 x 5050 (product ID 1643). There is also inserts for the inside of rings so you don't see through them.
The hole at the top is to allow you to use string to hang from somewhere.
The stands at the back are ok, but I've included the 123D file incase you want to make them better. I'm posting this on the 23rd so you can guess there's no time to fix and reprint!
I used an Arduino Uno that I had going spare to drive the LEDs. The code is included, I'm not a great coder but got the job done.
Fun project if you want to build it yourself or with your kids, used coding for the LED patterns, 3D printing design, wiring it all up, and patience! Cheers.
