jet pilot head with oxygen mask

A friend asked me for a model of jet pilot with oxygen mask, I remixed the head from the torso https://www.thingiverse.com/thing:516710 that can be printed, rediemensioned and replaced to the pilot head https://www.thingiverse.com/thing:1761697 that by license is not modifiable, I extended the mask tube and it is not high resolution. but it is usable ;D
