Summary

I designed this stands to represent flying miniatures in my D&D games.

I created them in this way to allow a creature to be above another creature without a problem.

I uploaded different sizes to represent 1,5m/5ft, 3m/10ft and 4,5m/15ft up in the air but is just indicative obviously.

Print it with the "back" on the plate and no supports are needed.

I added the raw files for Fusion 360 if you want to create a different size.
It's full parametric
