KB3D Nexus: The Insert (Modular GasMask System)

Core interface for the KB3D Nexus system.

Developed in the KB3D lab, the Nexus is The Modular Gas Mask System. At the centre of that system lies The Insert — An interface that allows any Nexus module to screw directly into the mask’s front port.

The Insert replaces the mask’s original front assembly, providing an attachment for any module in the Nexus range. Once installed, it becomes the permanent foundation that transforms a standard gas mask into a fully modular platform.

Nexus modules: 

• Standard 
• Table
• VacMount
• ReverseMount
• N40 Adapter
• Fleshlight

Please select your gas mask model from the dropdown menu to ensure you receive the correct Insert variant. If you’re unsure which version you need, consult the compatibility guide linked below.
