Printrbot Simple Metal - Wide, Isolated Feet Using Hardware Store Bumpers

Based on http://www.thingiverse.com/thing:593072 These isolated feet use bumpers that I found at our local Ace hardware store. See the bumper.pdf for bumper details.

Included are 2 options for front feet. One has a plain front and the other has holes for KCD11-101 Switches.

I use the switches to control the extruder fan and light. See http://www.thingiverse.com/thing:942779 and http://www.thingiverse.com/thing:725284
