I begin by transcribing the dimensions of my phone into a sketch in OnShape using digital calipers. I am cautious to take into consideration not only the profile, but the shape and location of critical features on the surface of the device including the home button, the screen frame, and the power dock.

I use the construction tool to convert this sketch information into a construction format, so that I can continue to use this sketch to build the bracket.

This is a product image of the wide angle camera that will be attached to my iPhone. I will need to be mindful of its size and location so that my bracket doesn't interfere with its attachment.

I've decided that it will be useful to have a model of my iPhone at my disposal so that I can check fit and dimensions in the assembly environment prior to manufacture. I modeled this representation of the device with all the features that I think will be pertinent to the bracket that will hold it.

I want the phone bracket to be positionable via a ball and socket joint. I design both of these using the revolve tool.

To allow for the socket to flex around the ball, I put in a relief cut, and pattern that feature around the perimeter using the circular feature pattern tool. I anticipate that getting the ball and socket interface correct will take a bit of trial and error

Designing the profile of the bracket that my phone will slide into. It's proving really helpful to have the model of the iPhone in my work environment, as I can pull dimensions from the computer, rather than reaching for my calipers all the time.

I'm ready to do a test print to make sure that the iPhone fits snugly inside this bracket. Clearly, I have not yet put much thought into how the object should look or ways of reducing its overall mass. Those will come soon.
