Skeletor mask.

More in my video:

As in the video I printed mine mask in two halves using 0.8 mm nozzle. Less supports but more post processing work than printing it in one go.

I took skeletor bust by @MironKampitakis from MMF

and made a mask using Blender. I removed everything except the skull, fixed it, thicken, smoothed and decimated.

3D Printed on Prusa i3 mk3s with 400 grams of PLA using 0.8 mm nozzle.
The finishing process is pure pain: sand, fill, repeat until happy.

Would be better to paint the inside black and/or maybe add tinted visiors.
