Shearwater NERD computer mount for AP Diving bail-out valve

thingiverse

I created this mount for my gen1 Shearwater Near Eye Remote Display (NERD) dive computer two years ago, when I could not find anything like it to fit an APvalves Bail-out valve (BOV) rebreather mouthpiece. The mount fits over the metal cover on the side of the BOV mouthpiece not being used and has a dove-tail slot for the computer to fit into, which is held in place by transferring the original set screw to the mount. Two versions have been provided, so you can pick which side of the mouthpiece you like the HUS display (left or right while using the BOV) . Pick the best print orientation for your printer and separate support filament capability. I used nGen filament for mine, but ABS or better should work. After printing, use a small file and knife to smooth the dove-tail slot were the computer to fits into. When done right the mount will slip over the metal cover on the side of the BOV mouthpiece with enough friction that it will stay in place and be slid off after diving when removing the breathing loop for cleaning.
