Parametric Brackets

I tried to find a parametric bracket SCAD file but couldn't find one to meet my needs. Had not tried to create anything on Open SCAD so I thought this would be a fun project. It is a very simple setup I used to make some under desk brackets with screw holes. You input the size of the device you want to to support width and depth, you can also change the thickness of the bracket, size of the holes and side tabs. You can also to a half bracket, which you can see in one of the pictures by unchecking the check box. Feedback welcome!
