Grado Driver Cup

A simple replacement cup and earpad holder for Grado headphone drivers or other compatible 46mm drivers (such as Symphones). I created it to match well with this outer cup: https://www.thingiverse.com/thing:4739087

The drivers will fit tightly inside with some persuasion so glue should not be necessary to hold them in place. A little hot glue on the interior surface of the outer cups is all that is needed to hold them securely together.
