IME epoxy doesn't adhere all that well to plastic, although if you add a little sawdust or fine plastic filings to the epoxy when you mix it, it might hold better. Esp. since you seem to be looking for more of a 'filler'. Failing that, you might try something like weldon or another solvent type of adhesive. If it's black plastic, a little ABS solvent cement might do the trick.
