Shelf Leg brace

I needed a shelf to simply put my game systems on my desk. I designed it to use 1"x10" (¾" x 9 ¼") top board but i used decided to use the scraps of wood i had around my shop.The legs are 2"x2" (1½" x 1½")boards Shelf can be as long as you want it.The one i made is 16" and it can hold a 225 lb man just fine.
