Designed a quick mount that fits natively onto the Ultimaker 2 Go. Back left corner (if viewing from the front). It uses one of the case screws and requires no additional hardware to attach to the frame. The 4 holes for the Pi are modeled with M3 threads. I had to drill out (just a little) the mounting holes on the Pi to fit M3 screws through. You'll need the hardware below. 4x M3 10mm screws 4x M3 6mm Spacers Enjoy!
