This Half-Mask was designed to demonstrate what a military respirator might look like in the future. Naturally, as a cosplay prop, it can be used or modded to fit a number of original concepts and characters.
If you want to attempt to one-shot this model you can go here.
I suggest scaling the model down to around 97% to fit most faces. Also, tree supports made this project possible.
This version was printed in Wood filled PLA on a QIDI X-Max and it took up most of the build plate.
(that is a build volume of 300 x 250 x 300 mm)
If you have a problem with retractions, make sure to print the propellors separately.
Lastly, if you hate sanding and painting…
Silk PLA looks good too 😁.
