Clip for Shearwater Nerd 2 on a rEvo DSV

When I bought my Nerd 2 in a shop, the original fastener wasn't compatible with the DSV of my rEvo rebreather. I made this STL based on the original fixation of the rEvodream. Simply remove the retaining ring supplied with the Nerd 2, and replace it with this one. I printed mine in ABS, but PETG will work also I think.
