Oxygen Cell

This is a typical oxygen cell used for rebreathers, oxygen sensors, nitrox analyzers. Maxtec 250, PSR 11-39, Sensoronics SS-25A, etc. I created it because I'm designing a new component for my rebreather and needed to see where the cells would fit. It's not a remix of photodiver's fastener, but I used his to help figure out the threads.
