Arduino Mega packaging???

Hi all,

I'm building a RepRap Prusa i3 and following the instructions available on the RepRap site. For some reason the base of measurement for setting the carriage lengths etc are the dimensions of the original Arduino Mega cardboard packaging box....

Would anyone be able to tell me these sizes:

a) because I already have a mega that came without a box
b) because I cant find out anywhere on the web
c) because I really don't feel the need to go and try and find one in a shop somewhere.

Thanks in advance - I hope someone can help me!!!

lol, interesting..

If you don't have an answer by tomorrow, I will stop by Radio Shack and measure a box..
