Dumbbell Nut with Inner Ring

I lost one of my dumbbell nuts, so I decided to design one from scratch and make it even BETTER than the original.
The design includes a star-type nut and an additional inner ring that keeps the weights in place and prevents them from loosening during use.

Modeled in Fusion 360
Printed on Bambu Lab P1S
Recommended material: PETG (High strength)

This piece works as a universal replacement for standard dumbbell handles.
