I am almost done with the 3 sides of my enclosure that I wanted to make structural. I can not begin to describe how happy I am with the results of this. There was so much drilling and so many screws and this took time to complete but it was so worth it. The cube is now so rigid I have to really fine tune the adjustable rubber feet to keep it from rocking on the tile.. Also this pictures shows how my X5SA 500 Pro will fit through a door completely assembled. The frame is wider than it is deep. So in building I have only mounted things to the sides and not a mm in front or behind the core metal frame. It is a tight fit and in some places I might need to take a door off it's hinges but this large format printer will fit through a doorway without loosing a single calibration.
