The original design I have remixed was a perfect fit for the camera, but wanted to keep the camera on top of the TV, with a much better mount as the one it comes with kept being knocked off.
You probably can't reuse this design as its made for my TV's thickness and border size, but you can reuse the concept to make your own.
Simply cut the bottom off the original, and replace with a three sided square to fit your own TV.
Then I decided I wanted the camera even higher, so added a large block to the back of the new design, so now it can be mounted on the TV both at TV height, and 15cm above TV height.
Added a temporary support pillar which just needs cutting off post print.
Best printed sideways.
