3D interlocking puzzle

I made this puzzle because we had a wooden version, but we lost a piece.

The design is extremely simple, but i wanted to try the animation mode in OpenSCAD.
So the piece generation for printing uses 10 lines, but there are 130 lines for animating the solution.

The Thingiverse customizer will only show the puzzle complete.
Open the file in OpenSCAD, In the customizer, choose "mode=animation", then use the [animation option](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_User_Interface#Animation) and set at least 200 steps.
