here is my version of a mechanical horse. i included the step file in case anyone wants to load it into software and build it. i animated it it fusion 360 and all the parts work together nicely. also this needs the links pins to keep the links together. you will also have to use 3d software to make a stl file of each part to print them and then assemble them.
