This is a base for an Arduino Uno R3. It holds the board flush with the top, and it uses the 4 mouting holes to hold the board in place. It is also the same height as a standard breadboard and is notched on both sides so it can be attached to a breadboard.
I have also included the sketchp file in case you want to change anythng
