Lifecam Metal Shelf Bracket

I purchased a metal shelf to hold my 2 3D printers, but could not find a good way to support a camera. 

It's a very basic bracket designed to slot inside the supports. 

Printed using JAYO Matte Black PLA
10% infill
0.2mm layer height

Shelf made by Storage Works

Model: 5-Shelf Multi-Purpose Shelving Unit
