40mm Gas Mask Inlet Covers

Inlet logos and covers for gas masks. Untested. 

Print rings with threads pointing up. Print covers with open side up, “face” down. Shouldn't need supports in general, but I haven't tested the thicker logos yet. Those might need some supports for the first 2-3 layers.

Updated: Edited to print face-up without supports. Also rotated the rings to match the print orientation without supports.

NOTE: There is a minor airway restriction. I need to fix this to allow for more airflow. Usable as-is, just be informed.

General disclaimer: Use at your own risk.
