This is the utility light design for the Tinkerlight system. It requires the lamp hardware kit. Full details of the system are at: http://robot50.net/projects/tinkerlight/ The lamp hardware kit can be purchased on ebay at: http://www.ebay.com/itm/LED-lamp-module-kit-for-3D-printed-lamp-designs-/152047252501?ssPageName=ADME:L:LCA:US:1123 You will also need your own USB power source. The utility light is intended to be mounted on a flat surface with small bolts, screws, or double-stick tape. It pivots in one direction and includes two cord keepers and bolt/screw holes around the base. The shade provides minimal eye protection from the very bright LED so this design should always be used with the lens mounted. The light source supplied with the kit is a neutral white (4000-4500k) LED that consumes 2.25 watts (450ma at 5 volts). The utility light will print on most printers without supports and a 6x6x6 build platform. ABS is recommended for its higher heat resistance but the lamp will work with PLA.
