This is a model of the Pokemon Geodude, done in the low-polygon style. Low Poly objects are things designed with a low amount of polygons, giving them a blocky or 8-Bit feel. They can also be easier to 3D print, as objects with millions of polygons are harder to process.
I designed Geodude using Tinkercad. After the body was roughed in, I exported an STL and imported that file into Meshmixer where I decimated it (reduced the number of polygons) until it looked good. Then back into Tinkercad, where I removed it's left side, duplicated & flipped the right side and stuck it to the left, creating perfect bilateral symmetry.

Prints with supports. I found it best to rotate the model appx. 30 degrees backward, mainly so that the upper lip is perpendicular to the plate.

Geodude is available to copy-and-edit on Tinkercad.com:

UPDATE, DECEMBER 2019
I edited the file (Geodude_LoPoly 2.0.stl) so that it could print without support and sit on the ground without tipping over.
