Summary
These are 3D temple pieces for the board game Tikal, improved for better fit. The design is essentially the fabulous work of makkuro (http://www.thingiverse.com/thing:284915) with one improvement: I made the interlock distance customizable (i.e. you can change the gap in the top of the pieces in which the next upgrade sits). This became necessary for me because the pieces of the original design were too tight and did not fit well together. If yours are too tight or too lose, you can experiment with this new parameter (click on "Customizer"). My experience is that 0.9 works fine on a MakerBot Z18.
