Lucina's Mask (Fire Emblem)

This is Lucina's mask from fire emblem. The mask will need re-sizing to fit your particular face. It will also require re-working with a hot air gun or soldering iron to get the appropriate curvatures. Then you can add a 1/4" elastic band by melting extra filament over then ends of the elastic band onto the edges of this mask. When the filament cools it will grip the elastic quite well (it melts some of the elastic into the filament).

I printed in black PLA and then went over the edges with a gold paint marker.
