I finally decided to change the design, here it is.

Designed to match the dimensions of a windmill made from a 100mm x 100mm piece of paper, two thicknesses: 0.2mm and 0.9mm.

NOT intended to be printed yet!

(ReplicatorG seems that would not find any problem though)

If you like to try anyway use the rawwing or the halfwhatever (and pleeeeease: feedback!)
