Parametric L-bracket with round countersunk hole

I was searching for a simple yet strong looking l-bracket for a wood cabinet/shelf I'm building. Azdle's parametric L-bracket was the closest I found, but it had odd shaped holes. I changed the design a little to have ordinary countersunk screw holes instead of the original ones.

I've never tried the customizer before myself, but this has some variables for easy adjustment of length, width, thickness, screw size, etc.
