Description

A foot for steel tube cantilever-type chairs (http://en.wikipedia.org/wiki/Cantilever_chair) such as the Breuer chair. The foot snaps over the bottom 1" metal tube. A short stub fits into the hole on the bottom of the chair to keep the foot in place.

ah good point. hadn't though of that. you could always either go with a pyramid nub so the angles arent too steep, or with a screw. but I suppose this works fine too.
Actually, you don't want to do that, because it's important the curve of the arms are printed with the perimeters. If you print it facing up, the arms will be done in layers, and therefore not as flexible and more brittle (meaning they may break when you try to snap them on). I learned this the hard way.
I'd imagine printing it with the open side up (as in the picture) would remove all overhangs. most printers should be capable of the 45degree angles.

Instructions

Printed with a .4mm layer height and 2 perimeters in ABS. Make sure to place the stl side-down (not facing up) prior to slicing. When you slice the stl, the side walls that grip the tube should be solid perimeters only (no cross fill), which will make them flexible enough to expand and snap over the tube. I found that even though it is an overhang with no support, the stub is short enough that it prints fine. Your mileage may vary, meaning you may need to clean it up (round off the bottom of any drooping overhang) with a knife or dremel tool.

If for some reason you need one without the stub, you can easily delete it from the sketchup file and re-export.
