Classic Arduino Mouning Plate

This is a mounting plate for the classic Arduino's Duemilanove/Diecimila/NG/Uno and any other ones that has the same form factor. This mounting plate serves three purposes:

• act as a spacer between the mounting surface and the board (3.5 mm)
• prevent scratching the mounting surface with the pins underneath the board
• prevent short-circuiting the board component pins if the mounting surface is metallic.

The mounting holes are 3 mm in diameter. They are pass-tru holes. The mounting plate is 2.7 inches (68.6 mm) x 2.10 inches (53.3 mm). Its overall height is 3.5 mm. The spacers are 2.5 mm in height. The base plate is 1 mm thick.
