It isn't easy to pick a category for this thing - an easy puzzle, a stress reliever or a decoration? What is for sure though is that it will spark the curiosity of anyone who sees it!
I made this thing to display as a mesmerizing brain teaser on my desk and got Léonie to assist with the YouTube video HERE.

I made two sizes of the Heart Gear thing. Pictured here is one of two which were 3D printed using Firetruck Red PLA filament. This one is the smaller of the two, measuring approximately 85mm tall, 85mm wide and 55mm deep. The stand was designed by RH Morrison and printed using Crystal Clear PLA filament.
