Bracket for Light Bar in St JOhns College Chapel

I was asked by our maintenance department to reproduce a small bracket that holds up a light bar as well as supplying the power to the lights. These choir lights have been in use for so long replacements are no longer available.
Using the last spare bracket as my guide I remade the original in Trimble Sketchup then i modified the hinge to create a stronger part for printing (green bits in above images)
