Blower kit for 12V DC fan, 60x60x25 mm

(Update)

I installed the blower on my Kossel mini. Length of the air hose was 590 mm, inside diameter was 14 mm. It worked out but one issue is big noise it generates.

Outdoor application is probably okay but using it as cooling device for Hotend is questionable IMHO. Running 12V DC fan at 5V is an easy option I'll try.

I made it to use 12V DC fan as blower for Bulbul Junior 3D Printer to cool hotend or to blow air on melted filament at the nozzle.

The impeller is scaled down versi
