Don't have an iPhone 4s, But you still want to enjoy Siri? Well now you can print your own version of Siri.

The main part of the microphone spins too.

Print part siri 1.stl with a low infill to save material, I do suggest using support/raft to stop the part from collapsing or deforming during the printing process.

Next print parts siri 2.stl, siri 3.stl and siri 4.stl I would suggest using a higher infill than you did for the previous part.

Once you have all 4 printed parts it is time to assemble them.

Start by gluing part siri 3.stl to the bottom of the u shaped part siri 2.stl and wait for the glue to dry.

Next you need to get the main part of the microphone part siri .stl and the rod part siri 4.stl and push the rod through part siri 2.stl (this should be a very tight fit). and just after the part has come through one of the arms of siri 2.stl you need to slide on siri 1.stl (this should slide on easy and move freely) and then continue to push siri 4.stl through until it has gone all the way through.

Now you should have a freely spinning microphone on a stand.

Congratulations you now have your very own version of Siri.
