Dell Latitude E6400, 6500 power plug reinforcement.

Designed out of a CAD program that I'm currently learning, Solidworks. The Dell Latitude E6510 laptop adapter pin has a very loose connection. This part was created to secure the pin and to prevent the motherboard from getting damaged. The part is not connected by using any screws and snaps on tightly because of tabs and lips added. I attached the STL and Solidworks file so please feel free to use or modify it if needed. Please provide some feedbacks on how I can improve it. Thanks!
