IKEA Wooden Chair - MAMMUT

Hey there!

I found this nice Wooden Chair here on [Thingiverse](http://www.thingiverse.com/ "Thingiverse Home").

The original author, [Tommy Kong](http://www.thingiverse.com/stronghero/about "Original author page"), made a mess with this model: the top part wasn't manifold at all and it was impossible to print (check [here](http://www.thingiverse.com/thing:873721 "Original Thing page") by yourself if you don't believe me :3).

So i decided to fix it by myself and to share with all of you
