KB3D Nexus: ReverseMount (Modular GasMask System)

Inward-facing attachment module for the KB3D Nexus system.

Developed in the KB3D lab, the Nexus is The Modular Gas Mask System. Built around a universal interface—dubbed The Insert—each module screws securely into the mask’s insert, allowing the function to be changed as required.

The Nexus: ReverseMount module is the internal counterpart to the VacMount. Designed for Deep-throat experts, it reverses the direction of a vac-u-lock compatible toy. The ReverseMount includes font ventilation ports that feed directly into the mask to ensure constant airflow during use. These openings may be obstructed, however are unobstructed if used with the 8inch "dong" from F-machine. As you screw the module, the toy gets deeper and deeper.  The exterior features a 40 mm NATO connector, allowing a blocker or filter to be fitted if airflow needs to be restricted or sealed.

Please select your gas mask model from the dropdown menu to ensure the correct module is supplied.
