Okay, this is it. It was made for floating/levitating discs by ZJchao (or Sorand or MASUNN), of which there are several variations (I have four different ones here!). There are two sizes of discs, with 4.2cm diameter and with 5.2cm diameter, and there are STLs/3MFs for each.
There are also two variations of the base that work, the black UFO one (5.2cm disc) and the metal square one (4.2cm and 5.2cm discs). There's also a white UFO version, but that apparently has a different (rounded) disk, so it is probably not compatible!

Here's the Amazon links, availability is fluctuating as well as the price, i paid between 44 and 75€ for mine:
UFO base: https://www.amazon.de/gp/product/B073GTKZLK/
Square metal base: https://www.amazon.de/gp/product/B071Y66S69/

I couldn't find out who originally makes these in China, but they're resold internationally under various "trading brands" such as ZJchao, MASUNN or Sorand.

The 3MFs are from Prusaslicer (2.3) and will probably not work in other slicers (well, Superslicer probably, maybe even Slic3r!). I only used PLA for all my prints, cause it's the only material that can bridge so far. And for the big 5.2cm version i had to develop a special technique of building a "cushion" of 2 layers of rectlinear infill each with 8%, 16% and 32% below the bridging/top layers (see the AniGIF in the pictures) because the top layers kept sagging and then delaminating at 0% infill. I used height range modifiers for this cushion, and a box modifier to add the red beak. Even if you want to print in singlecolor I suggest loading the 3MF and removing the red box modifier instead of loading the STL, cause only the 3MF has the "cushion" trickery! Use the settings below exactly, or the "cushion" won't work!

I printed this in all kinds of PLA variants that I had, Silk, glitter filament (all of the Fillamentum I had) and it really looks great and weighs almost nothing, which is key to it floating as high above the base as possible. Especially the big 5.2cm one has been carefully weight centered for minimum tilt.

A word of caution: Thanks to its hollow thin wall nature, this is really susceptible to any heat. I have seen these warp and deform within 10 minutes in a hot car in the summer! Even Perifractic's one had a slightly warped beak, the parcel probably sat in the California sun somewhere along the way. They will also most likely warp rather quickly outside in the hot sun. So if you have a good PLA+ that is more temperature stable, you may give this a try - IF it bridges as well as regular PLA, which is key!

The singlecolor version featuring Baby Yoda (performing his levitation magic ;-) in the pictures is printed on a Prusa MK3 in Ampertec neon yellow PLA and I swapped out the four white LEDs in the base for UV LEDs, which really makes the C= light up like crazy in the dark!
