About this 3D model

I made this lamp to test the accuracy, speed and reliability of my Shapeoko 2 CNC printer. I'm helping a friend make custom 3D printed LED lamps and wanted to show him a sample of what the machine can do. This object is completely hollow and does not require any supports. it took me 3 hours to print with settings under the "instructions" tab. http://youtu.be/QVbZ4bTnJTw http://youtu.be/ELo-Dct9RO0 Follow my project here: https://crunchysann.com/BL/projects/
