About this 3D model
This is a cordless desktop 120 volt lamp (uses the Philips L Prize lamp--60 watt equivalent) and it is powered by AA batteries through an inverter. I used a MakerBot spool and printed the shade and structural parts. Video at: http://youtu.be/omBZGBfSpK4 Instructions at: http://www.instructables.com/id/Cordless-120-Volt-MakerBot-Spool-Lamp/
