I do the same with 1/4" brass or stainless rod..you can make little clamps to attach them to a desk or an item by drilling and tapping a screw. to attach to the rod, drill a 1/4" hole, and a perpendicular one which you tap.
all easily obtainable at a generic hardware store and requiring only a hand drill
