About this 3D model

I had a problem. Over the last 15 years my wife has amassed a huge DVD collection and we do not have enough space for shelving to access them all. About a year and a half ago I decided to start ripping the discs to a media server. This went well initially but it was tedious. Ripping is a slow business and every hour I had to feed the computer another disc which was disruptive to normal life. I gave up. Recently inspired and armed with a 3D printer I decided to build a robot to perform the disc changing. Jack the Ripper Bot was born.
