I just mixed up GreaseMonkeys brilliant small power button model, it's been adapted to be used with the Wokyis Dock to combat the thicker edge of the dock itself and helps stop the annoying way you have to manhandle the dock and mac mini every time you want to turn it on.
All props and credit go to GreaseMonkey for his design.
The author remixed this model.
Switch and carrier extended by 10mm. Button and pin unchanged.
