Summary

This is a dreidel.

Rules of the game and dreidel descriptions:
http://en.wikipedia.org/wiki/Dreidel

Also found that funny video:

The two versions:
The four letters meanings are: "a great miracle happened there". I also added a dreidel with "pe" letter for "here". That dreidel's meaning is "A great miracle happened here".
All letters are derived svg-files from http://de.wikipedia.org/wiki/Dreidel

Instructions

Printing this part can be difficult due to the letter on the top side. So check if your printer is able to print the bridging part at the top. You can try to rotate the object for a better printing.

You can mount it on a M3 bolt with a M3 nut to build a dreidel. For a long rotation time you should add the nut part from Spinning Top ancestor (the M10 nut part). The placement angle of the M10 hexagon nut may influence the spinning result. Don't push the nut too far inside, else the Dreidel will not fall to one side. If the spinning time is too long, pull out the M10 nut a little bit.

Thank you.
I think a hexagon hollow center would be fine, too. 
The hexagon nut needs guidance from the side walls. So either you can use either 6 or 12 edges for the hollow structure.
 
If you place the flat hexagon side parallel to a side wall, then I think you will get an increased chance to receive that pair of flat sides letters. 
Yea! Lets make a loaded dreidel!

Very cool!

BTW, if you make the hollow center section an octagon, you shouldn't have any trouble with bridging, as the "corners" will be 45 degree angles, and the "top" should be short enough to bridge. Or you could make it a hexagon, with flat top and bottom - that should print, too.
