This is how I imagine a present in the Mario world would look. It is a mario question block with a ribbon attached. However, it can just be a mario question block without the ribbon. Or it can also double as an ornament. You can remove the ribbon piece and open this up and put stuff inside, but it is somewhat small and you may want to scale it up a little. I made this as one of my entries to the Tinkercad X-mas 2017 design competition.
This will require some superglue skills due to the fact that to make this 3D printable without supports I had to make the ribbons around the box and the bow 2 seperate peices in the file titled mario present ribbon. The file mario present box also has 2 peices, one is the box and the other is the lid to the box.
You may want to shink the lid a little. Mine barely fits, but your talking to a guy with an Anet a8 printer. You could either change the design, or Sandpaper or a knife may be helpful to make it fit.
