I recently purchased some Sugru, and decided to test it out on various things I have sitting around my lab.

One thing that has always been an issue is the underside of the Arduino.  The pins are really sharp and can scratch your desk surface.  Sugru to the rescue!

First, get your Favorite Arduino.  Here is my Mega.

Next, work your Sugru, and divide into 4 equal pieces.

Next, Roll each piece into a ball and stick onto Arduino where you would like your feet to be.

After that, find a nice flat surface.  I used a glass photo frame / shadow box that I had.  Press down moderately to make the Arduino sit flat.  Remove from flat surface and let cure for 24 Hours.  After it cures, Enjoy!
