Arduino Uno base plate with 60mm fan mount

This is a mount for the arduino uno R3.

It holds a 60mm fan in place within an case and on the workbench as well.

The design was triggered by my using an CNC Shell V3, where the stepper driver modules do need cooling to stay alive.

Especially one of the four screw heads would come close to Uno's electronic components. So a simple shim is provided to be put unter the screwhead.
