wind propeller easy

hello

 I wanted to share with you this propeller I made .
I haven't found a similar propeller, I've finished my exams and as it's hot I wanted to make a fan with my revision sheets.
Its particularity is that it's very quick to print and easy to modify.

to make it you'll need 12 m2 screws about 5mm long and bristol type paper, but I've done several tests with other types and shapes of paper and they didn't resist

to hang it, there's an 8mm hole because it fits well on fan rods, but it's easy to modify it to work with your rod. 
The model is quite simple, but I think the curves of the blades can be perfected. I'll let you remix it as you like.
