About this 3D model

Well, when you add some hardware component to your computer you always take those metal rails out of the back of the computer, but when you remove the component you can never seem to remember where those pesky metal rails went to. Instead of leaving a big gaping hole in the back of my CPU, I decided to print out a replacement rail that will cover the spot nicely. Simple little design and works. Not sure of how many people out there suffer from this same problem, but at least they can print one out if they happen to have a 3d printer, and happen to search on thingiverse for one :)
