This is the desk lamp 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 desk lamp has a spare design with an H base and an arm that can extend from about 9 inches of total lamp height to about 12 inches. The shade pivots and the base includes two cord keepers. The spot lens in the kit may optionally be mounted for a tighter pool of light. The light source supplied with the kit is a neutral white (4000-4500k) LED that consumes 2.25 watts (450ma at 5 volts). The desk lamp parts 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.
