Source for those clear shaft 9mm plastic snap in pots?

[(DEAD)fx]

Anybody got a good source for these? Been searching for a project and no luck yet. The clear plastic shaft 9mms that people use to illuminate the shaft with LED from underneath. Bueller? Bueller?

I think mammoth sells them. Or at least they used to. Haven't looked in a while.

Smallbear have those in 14mm size, IIRC. I haven't seen any in 9mm size.
