Hugo's 3D Puzzle

a 3D puzzle designed by my friend Hugo. The pieces fit together to make a 2x2 cube.

The interlocking elements fit together very nice and snug but when you first print it you may want to pass them through each other a couple of times if they are too stiff.

The file is arranged in a way that i believe should have the best printing results in the fastest time.

Post a picture if you managed to solve it (its not as simple as it looks)
