I received the 3D printed parts. I used good'old Shapeways to handle that!.
However, I had to drill and tap the mount holes for the Pi. It all fit together perfectly.
In the effort of portability, I am using one of the Pi TFT touchscreens
I used 2.5mm caphead bolts for mounting all parts. They fit perfectly into the mount positions.
Next update should be the final product!
