After overthinking many different ways to mount my GoPro Hero 3+ to my Eclips3D, I ended up coming up with this simple mount. It mounts on the front of the Z Plate, and uses the front bed leveling screw to hold it in place. It has the exact dimensions of the aluminum Z Plate, so it is held very firmly with this single mounting point.
You can watch this in use, while I am printing a second one, via this time lapse video.
