(This thing got featured in the thingiverse blog: http://blog.thingiverse.com/2011/05/30/this/ )When my daughter saw this thing ( http://www.thingiverse.com/thing:8859 ) she wanted to take the pieces off to have the "X" and "O" to play with for Tic-Tac-Toe. Since I had been messing with a case ( http://www.thingiverse.com/thing:8860 ), I decided to try to mash them together into a little travel Tic-Tac-Toe game.There is a little video of it building here: http://www.youtube.com/watch?v=nRKHwylv1MsThis is an original work, but is similar to: http://www.thingiverse.com/thing:7614 http://www.thingiverse.com/thing:8881 http://www.thingiverse.com/thing:8364The ZIP includes the OpenSCAD source. The OpenSCAD source is not an example of good programming. Just hacked together for fun.There is a logo on the bottom, you can delete that or replace it with one you like.1) Print.2) You might need to sand or tweak the lid slightly. With my printer it goes together right off the build platform, but I had to tweak quite a bit to make that happen.3) Try to remember when you thought little boxes with parts in them were cool.4) After you give up, let a kid have it, they still think little boxes with parts in them are magic.5) Wonder if the little pieces will break the vacuum as they rattle through it.
