cell phone on tripod

Can somebody tell me how to put the stl file the right way on the preview up there?

Description:

No screw, no clip just put your cell phone in it.

The hole screen is free

The buttons are free

And for all cell phones I've ever seen, the camera is always on top so it's ok!

You may need to open a cad and "push pull" some faces to fit your phone's size.
