About this 3D model
This is a quadruple sized square polypanel (double on each side) with standoffs in the hole pattern for a Arduino Uno. Can be used to build a polypanel case for your Uno or incoorperate it into a larger polypanel creation with custom electronics. The larger standoffs position the board heigher to make the USB and power ports more accessible in an enclosed configuration. I've modeled 3mm holes into the standoffs to accomodate M3 X 5 screws.
