Red Pitaya box (can be shielded)

This is a box for the Red Pitaya. I was inspired by "A shielded case for the Red Pitaya by hzeller", although the design has been made from scratch in Inventor 2016 and only the top cover is similar. As can be seen in the photographs, the analog part can be easily shielded (see post-printing).
The Red Pitaya easily slides on the bottom part, because the holes for the SMA connectors are slightly off center and large enough.
The fan is a 5 V unit recovered eons ago... it is 40x40 mm, with holes spaced 32 mm. The piece under the fan was needed, because without it the blades were touching the top cover. This portion may require modifications to adapt to different blowers.
