UPDATE 08.08: Weeeell I did some CFD simulation since this design doesn't really blow.. It showed that this config of the profiles and the curve of the blades leads to sucking in air on both sides.. Well I'll try to post some updates asap to correct this problem.
UPDATE 23.07: I'll be away this weekend, but when I come back I'll post plans for the rest of the assembly (not my design, it actually came with a magazine), but it's only fair you get the chance to blow air in your face ;)
A working (actually blowing wind) fan I made. The picture is a small motor assembly my roommate had laying around. Since the motor isn't all too powerful, doesn't blow very far. Feel free to print it, it has a 4,5 hex hole on the bottom. Turning direction is clockwise.
