Step 1: What you will need
The computer (of course)
A disposable drawing of the design (I obtained mine from Google, but if you're confident in your own drawing abilities you can make one yourself)
A drill (I used a Craftsman, but any brand is fine)
A drill bit (Due to the scale of my project area I used a 5/64")
Safety glasses (We are drilling through metal after-all)
Something to keep from drilling through the floor, desk, self, etc. (I just used an old wheel since the cover fit nicely over it. Although there are probably better ways, but I was on a low budget.)
Tape (If you end up using a paper design as a guide, you'll need this to hold it in place while drilling)
Step 2: Prep time!
Now, you print the image (I printed it into a smaller version so it would fit on the case).
Next, Tape the subject to the medium (case cover) on at least three sides so that it doesn't move.
