This mask was developed from the remnants of a broken mask (Refer to attached photo) that I 3D scanned and rebuilt with a mix of Blender and Meshmixer. The mask is suited for a child between 3 - 7 years depending on the child's size. The mask it self could obviously be scaled up or down to suit. Original mask was very thin so I have thickened the mask to minimum 2mm through out.

I chose to print at 0.1mm layer height but its personal preference on how much post processing you want to do.
