My Cube SL handles were falling apart so though I'd make a replacement (I was bored and wanted to practice surfacing in Fusion).

I printed it with TPU. I used low infill (5%) for the main shaft and 100% + 3 walls for the area where the horn connects. I also used 3 walls at the very top which interacts with the metal clamp.

Since the horn is probably not for everyone, I've included a plain version.

I screwed up the supports for the horn on mine (didn't use enough on one print, and used way too much on the other) but it's still OK for me.
