Sometimes the simplest mods are the best looking ones. This is the tale of a guy whose casing broke off his Cruzer flash drive. The clear-ifying process involved making a small mold with a bunch of wood and clamps, placing the naked flash drive in the mold, pouring clear resin in the mold and waiting for it to dry. Not only does it appear easy, it salvaged a damaged flash drive and gave it a cool factor.
