Nuraphone Replacement Earbud

I recreated the bud for a Nuraphone headphone since Nura was purchased by Denon and they stopped producing replacement earbuds. This is my first model in hopefully a lifetime of models based around the right to repair!

If you print some please let me know what you think!

So far I have printed some using Overture TPU, but I purchased some Ninjaflex TPU and I am hoping that those are more flexible and thus are more comfortable and closer to the genuine Nuraphone earbuds. I will update here if I find the Ninjaflex to be an improvement once it ships to me.
