extractor fan

Hi

I made this 155 mm fan to see if it can be printed, and that is possible.
these parts are made of petg with full support (because of the strength they need)
the filter housing is an option to filter the incoming or outgoing air.
the engine I used is a 12v motor with the deameter of 60 cm diameter 110 cm high with an ass of 8 mm diameter and 30 cm high the attachment of the motor is 32 mm apart from corner to corner.

the fan can be balanced with the help off the spindel in place just add or remove material on the blades.

this idea arose because I wanted a stronger fan that could also filter air and see if it was possible to print.

I uploaded a new design for the static pressure fan this fan is lighter and way easier to print hoop you like it.
