Cap for small momentary switch?

I am planning to make my saber with a small black momentary switch (http://www.thecustomsabershop.com/SP...itch-P285.aspx)
but rather than have that somewhat unattractive black button coming out of the hilt, what are some things I could cap the switch with, to encase the button in something prettier?

There’s this :) http://forums.thecustomsabershop.com...ght=Brass+caps

I've used similar methods to DC. Basically put any sort of nut or similar item on a drill and spin it against some sand paper to shape it.

This helps so much! Thanks!
