Sony Action Cam pistol grip mount

Hi All,
i wanted a comfy grip mount for my sony action cam for surf/water shooting. i used a model of a pistol grip and added a mount for the camera I attach a fishing trace to the camera and run it down the hole in the centre of the grip and attached it to a fin saver that straps to my wrist. Worst case I let go of the camera and the mount breaks everything will be still attached to me. It works out to be a comfortable position of the start stop button to use your thumb.

Fasteners/extra parts required: (all 316SS if using in ocean)

• 1/4" x 3/4" UNC hex bolt (STD camera mount, cut down to suit, could possibly use a 1/2")
• M6 x 30 button head cap screw
• M6 nyloc nut
• A fin saver (loops around the M6 bolt, straps to your wrist) or any kind of wrist strap.
• 50lb fishing trace (min 200 long, one end attached to the camera the other to the fin saver)

Please note i had some troubles with the export of the knob part and it was coming out a random scale, let me know if this is still a problem and I will try and fix it.
