One approach would be to make a casting of the outer part of your ear
canal with something like ShapeLok. I've been meaning to try that myself.
One would want to cast around a hollow plastic tube
to vent air back into the canal in order to avoid
an ER visit to remove the finished casting...

I wasn't suggesting pushing it all the way down to the eardrum, silly.

Doesn't matter. A half a gram of media is enough to rip your eardrum
if you are pulling a vacuum on it as you draw out the casting. Even if
it only goes half way in.
Good call, Winston.
