T shape insert for alimimum profiles

while i was working on a project with extruded Aluminium profiles i ran out of T slot nuts.
I realised it after fixing the frame. so i decided to make a small t slot of my own which only requires a M5 nut and bolt to latched onto. i had some electronic boards of various shapes which requires brackets , but this can be adjusted to various sizes and shapes using the clamp provided with it.
