I knew that this sketching would take forever to actually dremel out by hand, but I knew perseverence would win out.
The lines don't take that long to draw, but the etching was another story. The sides took around five hours each to do, and the top panel took around ten. I tend to etch until I can't feel my arms - then it's coffeebreak time!
I used some tape to put the three sides together, so that I could get a feel for what the case would look like.
