Video of how much my Z rods wobble, despite zero sign of Z wobble in resulting prints.
See http://goo.gl/89MTE and http://goo.gl/R2CAF for higher res pictures of the part in the video, and see http://goo.gl/10G94 for the Z-coupler I use - it's simply vinyl tubing as used for aquariums and available in most hardware stores. Also relevant is that I use M6 rods instead of M8.
