Mounted upside down with camera hanging downwards. Used this camera mount screw to hold it into place:

The author remixed this model.
Added a center stopper at the joining point of the 2 rods to keep the mount from sliding. Also printed at 99.5% scale for a slightly tighter fit. Removed extra support, seemed to be in the way of the wire.
