Vertical Board Anchor (Parametric)

This thing will keep vertical boards (such as laser-cut printer feet) from sliding around on a surface. It's fully parametric, well commented, and very quick to print.

The STL and default values are suitable for holding the 6mm feet of a Printrbot LC in place using #4 wood screws with 82-degree countersink angles. There's an STL for #6 screws as well.

I use this as part of my parametric printer enclosure, which is available here: http://www.thingiverse.com/thing:39787
