Merry Christmas! This is an Ophanim (aka "wheel" or "throne") angel as described in the Bible: four intertwining rings lined with eyes and four wings, with a fantastic flame at the center. The rings form a freely spinning gyro/gimbal, and the wings fit into ball-sockets on the outer ring.

To assemble the model you will need:

the body rings (print-in-place)
two wings for the left, and two more mirrored for the right
either the complete fireball or both split halves

I recommend either hanging it like the picture or drilling a small hole in the bottom to attach to a flight base (I did both for after-holiday use as a mini). Note: I wouldn't attempt this model with FDM printers, the one in the photo was printed with my Elegoo Mars. The details are too fine, especially the wings.
