This is a Remix of "steventwheeler´s" "Ender 3 Raspberry Pi 2/3 mount 2 rails - LM2596 - No fan or ports"

I don´t need a LM2596 but could use the free space for a Rasberry Pi Power Button and a LED Status Light.

The Diameter for the LED- and Power Button-Holes are:
LED: 8,25 mm
Power Button: 7,25 mm

These are the Parts I used:
Power Button: https://goo.gl/Lhqu8M
LED: https://goo.gl/diY8he
LED SnapIn: https://goo.gl/GTgDf6

For the Power Button and Status Light I used these Guides from howchoo.com
