Wobbler Hobbler

This is a derivation of twotimes\' excellent wobbler arrester. There are several changes. First, a new z-guide replaces the clamp. It performs the duty of connecting the smooth stabilizing rods showcased in twotimes\' approach to the acrylic stand. This z-guide bolts through the top of the acrylic stand using the holes also used by the z-floats. As with twotimes\' approach, the z-floats connect the acrylic stand to the threaded z-rods. The z-guide and the z-float sandwich the acrylic stand.

Second, the z-float has been modified. A fifth bolt hole has been added to it, allowing it to be bolted to the z-guide. This provides extra support to the cantilevered z-guide.

Third, the z-guide has a spring built into it. This forgives any expansion in the acrylic stand due to heat from the heated build platform, as well as imperfections in the alignment of the smooth stabilizing z-rods. At the same time, it\'s sufficiently stiff that almost all wobbling will be eaten up by the more flexible
