MSA ESPII to FM12 VPU Adapter

thingiverse

This is a prototype adapter to use an MSA ESP II VPU on an FM12 gas mask. It has a cut-out to accommodate the built-in drinking straw, however there is no way to actuate it through this adapter yet. The affixment to the mask is currently a poor friction fit, but I plan on improving this soon. My goal is to be able to use these adapters without modifying the original mask or the ESP II. The VPU clips onto the adapter as it would normally. The pictured model was printed on an AnyCubic Photon in AnyCubic black.
