I saw some models of the comunity and decided i wanted something different to use on my LARP character. Some inspirations were:

I designed this based on my ear size, and didn't make extra long as i intend to use while running and fighting with LARP weapons.

The main features i wanted was a "c" like insertion format, where i could hide part of my ear inside, and the bottom and upper part of the "C" would give some mechanical support with some flexible filament.
