I created this stand for my TinyG electronics that's connected to my Shapeoko 2 CNC Mod I have built. It was designed in Solidworks. It's pretty straight forward. It's made of .25" Acrylic and a particle board used for house building. Ironically, a full sheet fell off a truck in front of my house and they never stopped to get it. So, it was free and now a part of my projects :+) What a Blessing !

I got everything from Ebay.

The toggle is on/off switch
