Once upon a time, I printed this: Cat Ears for Headphones by usernamexx - Thingiverse 

Today it broke :(

So I designed my own to improve upon the design. What makes these better in my opinion is that it prints in a single part and is hence more durable. Another problem I was having with the cat ears above was that the hair tie would slip off because my headphones (Arctis 7) were too wide.

I printed it with the new fuzzy skin feature in the Prusa Slicer to give it a more organic look, especially reflection-wise. It's designed to be able to be printed without support. I like how it came out and I hope someone else might find it useful as well.

You can add different colors by changing filament mid-print as I did. In case you're interested, I printed this on my Prusa Mini+
