Nipple broke off in Zipp 415 rim

[Jaguarundi]

How to get it out? It makes a racket. The rim is a Zipp 415
-- the 38 mm deep one they confusingly use in the 303
wheels. There is a lot of "carbon fuzz" inside the rim.
There also seems to be a kind of semi-attached plastic film
on the inside. The rim was purchased in June of last year. I
have spent over an hour using the trial-and-error method, to
no avail. I'm not even certain where the nipple is in the
rim. I have shown it to three other people -- none of us can
pinpoint the source of the rattle closer than a span of five
inches or so.

Thanks.

Bounce the wheel on short napped padded carpet.
Vision the nipple bouncing inside the rim cavity and try to have gravity move it towards the valve hole. This is done with the tire and tube removed. You may need to rotate and tip the wheel to make this work. Ultimately the nipple will fall out of the valve hole.
It works for removing the small bits of aluminum that are left inside rims like Mavic Open Pro

It it's steel maybe try a strong magnet to move it to a
point where you can get it out.
