I made my pinion caddy out of a 1/4" piece of Kydex that is 5" x 8"
Sized and marked where I wanted all my pinions to be size wise, drilled the holes and cut down some (I believe it was .100") rod (Piano Wire) into 1 inch lengths.
Forced the rods into the drilled holes in the kydex
This caddy lays FLAT in my tool drawer, and goes all the way to the back of the drawer - holds ALL my gears from a 35t to a 65t 64 pitch pinions, and they are stacked 2 gears high.
(I think the materials cost me 10 bux, and about an hour and a half to drill and cut.
