Laser Cut 19" 1.3U Rack Mount Shelf

I needed a shelf for a network equipment rack and decided to try and make it on the laser. I think it came out pretty well. Shelf dimensions are approximately 17"x9". I've called this a 1.3U shelf since it uses 4 rack mounting holes, but it's probably more like 1.6U once you include the bracing on the bottom of the shelf.

The shelf is designed to be made out of 1/8" (~3mm) material, and fits on a single 12"x24" sheet. I've put letters on the various tabs and their corresponding slots; bet
