Vex Robotics EXP Cortex Bracket
These are made for the new VEX Corex. I made a larger bracket the screws into the outside holes where there are nuts to screw in to. The smaller bracket screws into the middle 4 screws and just clams the cortex. I do recommend drilling out the holes slightly to make it easier for the crews to pass through the brackets without cracking the brackets. I also recommend only snugging the screws rather than tightening them all the way down.
