3d printer unboxing and first operation

I'm going to buy a 3d printer, and open the box and try to get something printed on it. This way y'all can see what it takes to get started with 3d printing. I may open the box before the meeting to verify package contents, but I'm not going to cheat and set it up before the meeting. There exists a possibility that I won't be able to make it work in the 2 hours our meetup is scheduled for, but I prefer to think positively.
