One Piece Ball Spinner

Wanted to design a single print spinner and came up with this. Designed in Tinkercad and printed on my Ender 3 using Solutech Glow in the Dark PLA. I printed it on a raft for the extra support and had to do a little filing but otherwise post-print work is minimal.
This was designed more as a proof of concept than for looks, I could see easy ways to improve the overall aesthetic.
Added 3 more wings on the original design for more weight and it just feels better in the hand. I am working on a ball bearing one-piece design. Originally had 8 small outer spheres but too much of a gap was left and they could pop out. Redesigned with 10 outer spheres and currently printing it out. Included the stl for those that want to try it.
