Arduino Uno Model

This is just a placekeeper object to aid in designing boxes and bumpers for the Arduino Uno (or any derivative with the same form factor.) I included the Autodesk 123D file, I do not have the ability to save it in other formats but perhaps you can import one of these two. Enjoy!

I added a version with a little less detail on the ports and exaggerated the height and width of the ports by 0.5 mm in each direction. This should be better for using the model in boolean operations. I also added a blank board to serve as a generic shield. It has 2.54 mm ridges on the bottom where pins would be.

The dimensions came from [this image](https://www.wayneandlayne.com/files/common/arduino_uno_drawing_1000x703.png) by Matthew Beckler. Thank you Mr. Beckler. Another good source is, (as always,) [Adafruit](https://www.adafruit.com/datasheets/arduino_hole_dimensions.pdf).
