Lifegard II Backplate for Metal Clip

Slight modification to the backplate on Jason407's excellent LifeGard II Model.

This backplate is designed to mount a not screen accurate but very, very strong #620 4-Point belt clip from Theclip.com. Mounts with M3 hex nuts and M3 screws.

Update 3/21: Added 3mm screw holes with a 6mm wide, 2.5mm deep recess that line up with the anchor blocks on the Lifegard body. Use these as convenient drilling templates when attaching the backplate to the Lifegard.

Update 8/9: Updated the backplate
