Here is my levitating LED version. I had to scale model slightly so the orb inside would fit on levitating disk (5.5cm or 2.2''). I made levitation device myself, but it took a lot of time and money and you can buy it a lot cheaper from Aliexpres for example (search for: Levitation Display Stand).
I used 12V battery and 3 blue LED's inside the orb (printed in clear PLA) with small slide switch on top. At the bottom there is a hole for levitating disk and you can access battery through that hole too.
I put one LED inside each orb on the case (printer in clear PLA) and solder them is series (4 in total) using 24SWG enameled copper wire. After I wired everything I painted the wires so they are barely visible.
It took a lot of time to print it and then to put everything together, but I'm happy with the results. Here is a video so you can see that the orb inside is actually levitating.
If you need any help please message me. Comments and feedback are welcome :)
