Stanley’s professional organizers are extremely durable, easy to stack and store (even vertically), and best of all the 25 compartments are removable, swapable, and reconfigurable. I now have six units in use holding all types of small parts and components – hardware, PVC fittings, servos, electronic components, grommets, and the list goes on.
These organizers are as affordable as they are portable, and will set you back about $15-20 each. You can find these organizers online or at home improvement stores. Our local Home Depot and Lowes stores don’t seem to carry the 25 compartment version anymore and instead only carry the less useful (from a small parts storage POV) deep 8-compartment organizer.
A word of caution – we have seen knock-off versions of these organizers, and while they look quite similar, their build quality leaves much to be desired. The Stanley version is manufactured by ZAG (now a Stanley daughter company) in Israel (at least as of May 2009).
