About this 3D model

The Hadron is a great 3D-Printer, I was one of the first user and I don't want to miss it. This is one of my improvements for the Hadron, it's derived from brnrd's thing:38534. Update 23 Jan, 2013 Going on with the Z-Wobble improvement the diameter can be reduced to 10mm. Update 27 Jan, 2013 Increased tolerance to off-center. (14x11.2mm)
