KB3D NEXUS - The modular Gas Mask system: VacMount Module (Patreon)

The 5th module in the KB3D Modular Gasmask System refresh/standardisation. This modular system is now called NEXUS.

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 Insert is not included in this post.

This post contains the VacMount Module. The Vacmount module has a Dildo mounting point on the front. There are also integrated air holes to insure easy breathing. Recommendation would be to print with high infill for strength.

Available masks:

S10/FMJ-08 - Compatible

FM12 - FM12 only

MF11/FMJ05 - Compatible

GP5 - GP5 only
