For TennoCon 2019, I was asked to make some props for TennoCon 2019 with the Corridor Crew. I had to model out a Void Relic for the job, and Warframe/Digital Extremes has given me permission to share the files so other people can make their own.
Things you will need:
Transparent Filament is mandatory for the Relic Sphere top half -- you will need to back mask the sphere so light doesn't shine through. I used a couple layers of black spray paint on the back, and regular filler primer on the front along with normal paint.
I used an Adafruit Feather Bluefruit to remotely control the lights. I connected it to a USB external battery with a USB micro cable wired to a switch on the bottom. When the switch is turned on, it provides power to the Bluefruit by waking up the USB battery. I also wired a USB micro extender to the USB battery's charging port, so it can be charged once the system is sealed inside. The lighting system is standard WS2812B GRB LEDs wired in a zigzag pattern and hot glued to the pucks. Watch this video for a glimpse at how it all works: https://www.youtube.com/watch?v=TEjxuTM6sCw
You should not sell prints of this model, as I am releasing it via a noncommercial attribution license. If I see it on Etsy, I'm going to have to kindly ask you to take it down.
