Merged Clamp for Logitech 270/310 Mount

The original clamp of the [Ball and Socket Webcam Mount for Logitech 270/310](https://www.thingiverse.com/thing:2368146) broke nearly instantly as I screwed it in. I decided this is a relatively bad design as it will always break easily. To make it better, I have merged the screw-in ball part and the clamp itself, but left the big screw untouched. Note that you now need supports to print it, but it is infinitely more durable.

I have also included the Blender files in case you want to edit it
