A small foot that can clip onto the 6mm bars of a Mini-Mendel/Huxley RepRap printer.
UPDATE 5.6.11: I should warn that I created these feet before constructing the Z axis, and it may be the case that these feet are too short with all the gears and mechanisms under the Z rods. At the moment there are a few millimeters clearance, but I have not yet installed the motors or Z rods completely. I will update this description once I complete the build.
UPDATE 11.6.11: If the feet are placed on the lowermost bar (front and back) then there is plenty of room for the Z axis. I've attached some photos showing this.

I found that it will print fine with zero infill with 0.4 Thickness and 0.5 W/T Ratio. Otherwise the the infill motion will vibrate the printer quite a bit. Your mileage may vary.
Pressing the still-warm piece around the metal rod makes for a nice, tight fit.
