Since there is no multimedia dock sold by Motorola for my Defy, I decided to make my own.
I had initially planned a dock and modeled it in ProE. (See here: Phone and Stand)
But then due to some practical difficulties in making the dock as per the design I made a few modifications to suit the material and tools that were available with me. And hence here it is.
As you can see in the image below there is a sponge that is stuck to the base to act as a cushion to the phone
The thing that changes the phone to dock mode is the magnet. Basically a Multimedia dock consists of a magnet so that the phone can sense the presence of the dock. So I stuck my own magnets and made it like this.
