Summary

A gear-pyramid that can rotate through various configurations, with a crust and inner-body in different colors (dualstrusion).

Instructions

This is a derivative of the Screwless Heart Gears by Emmett www.thingiverse.com/thing:12208 ( many thanks to him for sharing the OpenSCAD source), as well as thingiverse.com/thing:24675 by CrazyJaw, and the Crusty Micro Gear Heart http://www.thingiverse.com/thing:33668.

There is a full plate with all parts (two stl files: one for the body and one for the crust, use Ctrl+D in ReplicatorG), as well as two gear sets if you do not want to print the entire plate (two files each). It seems I get better results by printing the sets separately.
I'll upload the OpenSCAD files once finished.

The pins are the same as in Thing 24675, I simply provide them here for ease of downloading.

Tip for mounting: Large gears go on large faces of the inner core. I advise to put them first, followed by the tip of the pyramid. Keep in mind this should look like a pyramid at the end :) The small gears are actually slightly different from each other, so put them in place without the pin first to double check.

The corners are very sharp so handle with care.

Enjoy!
