i made this nerf dart tip that doesn't hurt (or at least hurts less than the ones with hard tips) and it flies great I don't know how it compares to the original because i only have the shitty chinese ones but it flies as good as those. It's made out of two parts one in pla and the other in tpu, you glue them together and to the foam and it's good to go. I made it because i have cheap darts with hard material on top that hurt.

tips:

-use the print profile for best results but change the filament to yours.

- if you want them to hurt really bad you can skip tpu part I'm not responsible for anything it might cause though.
