Hi there !

I have just added a new improvement for my 3D printer, the legendary # alfawiseU20! This improvement is essential if you want:
- to reduce the air flow sound from your PSU,
- to avoid that air flow from your PSU interferes with your printing (it depends on your PSU placement).
- No glue : an only one magnet allows you to fix it on your PSU !

As usual the STL file of the nice air deflector is available video's description !
