It's a disc golf driver namned Skyeel. Version 2 is an update with smoother bottom edge, for a cleaner release. This makes it a bit more understable also. Dimensions should make it PDGA approved

Rough estimate of flight numbers (based on throwing it to 100m / 330ft):

Skyeel 2 - Speed 10, Glide 4, Turn -1, Fade 1
Skyeel - Speed 10, Glide 4, Turn 0, Fade 2

TPU 171g, layer height 0.2, wall line count 10, top/bottom layers 6, infill 90% (lines)
PLA 162g, 75% infill

Preferably printed in flex/TPU plastic to not make it dangerously hard. Shore Hardness 95A or a little harder will do.

Can be printed in two parts. Adjust inner ring hight (z scale) to make it more overstable or understable. Higher ring makes it more overstable and lower ring makes it more understable.

A reminder if you using Cura, set "Build Plate Adhesion" to "None" to make the disc fitt in the printer (Ender 3 at least).

If printed upside down a 2 mm support under entire disc might make support removal easier.
