This is CogBot: the 3D print in place robot with gears that allow for movement. It has an inner body section with moving legs that drops down, this can then be tilted, and the layer lines will hold it up. This will also print in most materials, like in the pictures above, you can easily print and polish this design with a metal composite filament which will give it a really cool old look.
As always this was designed in Fusion 360 and can be printed without supports, and although it can be, I would recommend not printing with a raft, as this may affect the movement of the gears. Also, the more you move the gears, the smoother the movement will become, and if you have any feedback then please be sure to comment. Thanks for printing :)
This does not need supports whatsoever, and rafts are not recommended as this may affect the smoothness of the movement. If it is not moving smoothly, turn it quite a bit and it should free up. If not, then move the central body up and down, as there's probably some overextrusion (stringing) inside the gear mechanism. To get the part to move, push down from the top on the central part, and if the gears are stuck, push them upwards individually. If you wish to print with metal, then do the same process, but make sure to be extra careful with the gears. To get a minimal polished look just rub it with wire wool or sand with high grit sand paper, then if you want you can further polish this with cheap metal polish.
Note: resizing the model (especially downsizing) will affect movement in the design. If you wish to have a small version of the model, make the holes between joints bigger, or ask.

Can you please help me,as the gears keep falling and if I glue them, probably they will not rotate the head. Did I not print it correctly? Thank you :)
