NIKON P900 Red Dot Mount V5

This is a adapter for Nikon P900 so that a Red Dot sight can be mounted.
I have used this "Hot shoe adapter" http://www.thingiverse.com/thing:241592
for the actual Red Dot mount. Thank you!

Now I am up to the two part Version 5. :-)
I normally leave the front ring mounted on camera, and attach the RDS mount when needed. Use a hair rubber band around the EVS to secure the RDS. I use foam tape where the upper part rests on the camera.
