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 40x40x11mm pc fan with motor size of 24mm.
Optimize for 0.4 nozzle, 0.1mm layer, 2 perimeters set, 20% infill, no support needed.

• In 1th video I show the test of slim version and the assembling of boxed version.
  
• In 2th video how to work the adapter.
• In 3th video the inflating bug test.
