About this 3D model

Hi, I will try to make things "3D compatible", means without or minimum supports and no raft. I'm a maker like you, so don't like to have to eliminate supports and damage print or loose 3D filament. I will make 2 different front things: one for protect fingers to propeller but wind is not so strong to the second front thing without finger's protect. I have try the second with my fingers and i'm not injured... but for children, it's not safe. I have try too without front print, that's cool too :) Needs : You will need a small drone motor 5V and his propeller, and usb cable (like old mouse). IMPORTANT : don't forget to inverse propeller and polarity wire. If not, fan turn in the wrong sense (polarity) or not make strong wind (propeller). Hope you will like that.
