Used this to design a headpiece based off of a Pinterest. Easy to cutout and modify. Also, scaled down after combining to fit on BambuLab X1C printbed. Cutout the princess peach headband for the sizing. There are small 2.2-2.4mm by 2mm deep holes that you can make pegs for to attach different things.

I ended up cutting off some of the bottom with cutters as my first version didn't turn out perfect and I wanted to conserve plastic, which is why the picture is slightly different than the model.
