Based on the Arduino Duemilanova models I found in Google 3D Warehouse. It seems that one Arduino model is based upon another in the Warehouse in an evolutionary growth, so it’s hard to give credit for the original design. Suffice to say, I’ve had to revise and add stuff, but I didn’t start from scratch.
Anyhow, my goal is to show every single jot and tittle on the Arduino board without recourse to phototexturing. Then sometime this month I plan to scale it a thousand fold, set it on a foundation and erect observation platforms and conduct a guided tour . . . it’ll work. Trust me.

This is fantastic! Do you have this in the 3D warehouse? I am playing around with some designs and this would be super handy. Of course, I could do it myself. But this could save me many hours!
Yes, just do a search on ‘Arduino Uno.’
