Plastic Clip-on Spacers for Arduino and shields

Hey,

I was just trying to track down some spacers that would easily clip an arduino shield to an arduino. I think I found some good ones, so I thought I'd share the details here. I've only found them for sale at Digikey in lots of 1000 ($0.097 each):

Richco has samples, if you want to try them out. Those two above are meant for .125" diameter, which should work for the Arduino.
