Arduino Mega 2560 Bumper

I've seen some other bumpers out there for the 2560 but none seemed to fit for some reason when I printed them on my Makerbot Replicator 2.

So, I took direct measurements from my boards and worked up my own bumper. Created a thick-walled version and a thin-walled version. I've found the thick-walled version hangs onto the board better because its more rigid but the board doesn't fit back in the box with the thick-walled version (#tradeoffs).
