Kig mask snorkel

A breathing tube for kigurumi, designed to divert the exhalation opening to prevent moisture buildup inside the mask.

It uses a mouthpiece similar to a diving snorkel for breathing, so the trade-off is the inability to speak? (What a strange scenario)

The design allows for the installation of a one-way breathing valve, or you can choose not to install it (it's a bit too small; if a one-way valve is installed, the single-tube intake and single-tube exhaust might not provide enough airflow. Without it, dual-tube intake and exhaust would be better, but I haven't tested if it gets stuffy with prolonged wear)

Installing the breathing valve requires cutting pieces.

Other materials are as follows:

Breathing valve membrane, needs to be cut to the appropriate size; the printed part includes a cutting template

Snorkel mouthpiece, the mounting opening needs to be trimmed to about 1mm before the recessed slot on the inner side

10mm outer diameter air tube (silicone tube might also work? But would it be too soft?), this breathing tube needs to be cut to the appropriate length and glued to the connector
