Mario Question Block from Adafruit Part I

This is my next project, from a tutorial on the Adafruit Learning System.  I enjoyed working with the Pro Trinket in the Donkey project, so I thought this could be interesting.  Also, the enclosure is 3D printed, and I am intrigued by 3D printers, so that was a draw.

I found a local 3D printing service through http://www.makexyz.com/ and this is what he produced:

It's pretty good. The top does not fit right on the body, so I'll have to do some modification, and it's not as clean as I'd like, but I'll work with it.  It cost $20 for the print, including mailing it to me, plus $3 for the service.  When I get the time, I will do the modification to the enclosure and the construction. I have the parts, so it should go OK.

Here's what I've learned so far:

• At first I thought the print was backwards, because I was comparing what I got with the photos in the tutorial. However, when I took a photo of the print to send to the guy who printed it, I realized that the photos reverse the image...so I'm believing that it's OK.
• In all the photos in the tutorial, it looks like the handle is part of the print. The printer said no, then I read the fine print in the tutorial and it said "attach a handle--you figure out how."  But, the handle DOES seem to be part of the print.

I have posted questions on the Adafruit Support Forum.  When I get some clarification I'll pursue this further. Meanwhile, I'm kind of stuck.

More when I get to construction.
