Grado Headphone Earpad

Grado headphones are awesome, but the foamy ear pads dissolve way to fast. So I decided to try to make some out of NinjaFlex rubber filament. The fit is perfect on my circa. 1994 SR80s. Not sure how the can size has changed over the years, but they look to be pretty similar shapes.

The comfort of this design is not as good as original foam, but I expect tuning of build parameters could help soften them up.
