Micro servo - Size is accurate but if your making sockets don't forget to make it slightly bigger or it won't fit!
Idea is to use this to mesh in other designs so that you can see if your positioning is correct. Then you can make a slightly bigger version and use this to make a boolean cut in your model.
Socket and CAD files also included.
Updated after using freecad to get rid of non-manifold faces, etc.
Just print it out, or use in cad models to help position your servos. CAD files (exported from freecad) are also available so you can build your own socket if the supplied ones don't work for your project.
It's a good idea to just print out the socket before adding to your project so that you can test the exact fit of the servo, cable and horn access, etc. Make sure you give yourself enough room to snap the servo in once you print your whole model - that's why one of the sides is short in the socket design.
