PcFanBoost Box - for xbox360 fan / 70x70x30mm conversion

Hi, this is last version of my adapter to increase static pressure of the pc fan. I made it to recycle old xbox360 fan but it also use for some 70x70x25mm pc fan.  There are many different dimension of fan, check the measure in image.

In this all in one version there are  not  obstruction between blades and adapter. This increase the efficient of flow air and no comeback air when it run freely. I add one blade respect separate adapter.

Optimize for 0.4 nozzle, 2 perimeters set, 15-20% infill, support touching bed.
