This is a dreidel.Rules of the game and dreidel descriptions: http://en.wikipedia.org/wiki/DreidelAlso found that funny video: http://www.youtube.com/watch?v=iS24dsLTuW0The 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/DreidelPrinting 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.
