Modular Paper Princess Crown

Well... I see a lot of Covid19 protective face, one of them give me an idea for my little children.
Replace the plastic paper by a paper crown!

I use this model excellent from the ULB:

As protective face shield it's excellent! I have print several of it !
I modify the scad file to have only one ring ( https://gitlab.com/fablab-ulb/projects/coronavirus/protective-face-shields/-/blob/master/PFC-Headband-Light-3DPrint/anti_projection.scad )

So to make the hole on the paper, I creat a hole punch with one all:

Easy and without any risk for my older children !

Cut a A4 paper in two part (from the long edge).
Like the tutorial for the protective face shield, 3 holes (with my OnePunchHole) and here we go

All the things are tested and approved by confined children !
