Hi, this is last version of my adapter to increase static pressure of the pc fan. 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.
This version is to convert typical 60x60x25mm pc fan. There are many different dimension of fan, check the measure in image.
Optimize for 0.4 nozzle, 2 perimeters set, 15-20% infill, support touching bed.
