This might be one of the most futuristic looking gear mechanisms you’ve seen on Thingiverse. User otvinta3d released a great model demonstrating the Eccentrically Cycloidal Drive Model by EC gears. It’s a drive gear mechanism with a gear ratio of 1:9 in a very compact design. Achieving such a ratio with conventional gears, in the same compact body is very difficult. 

We 3D printed this model with colorFabb nGen and at 0.08mm layerheight the gears run very smooth. This model contains only a few parts parts and is easy to print and easy to assemble.
