Have you tried creating a 3D Printed model of the Nyx and then use Quantum Levitation that can be seen in this video?
How it would work is a, channels would be built into the Nyx model during its 3D Printing process. The channels are then lined with a sapphire crystal coated super conductor, as well as making certain to leave a fill port for the liquid nitrogen. The model is then bonded together and voila. Quantum Levitation.
