3D Printed Interlocking Puzzle

I modeled this after those 3D wooden puzzles you get that require you to use a bit of brain power and thinking to build it. It's a great "Thingi" to keep on your desk at work or coffee table at home for people to try complete. Challenge your friends and family to see if they can put the puzzle together.

Here is a link to a video showing you how to build the puzzle. I challenge you to give it a try first though :P

***NOTE*** The success of building this puzzle depends on the accuracy of your printer. Some parts maybe be a tight fit if your printers accuracy is not great. I've scaled the gaps up a tiny bit to compensate for that. Print it and let me know how it fits together.
