A few months ago I upgraded my cell phone to the Galaxy S3. It's a great phone. One of my favorite features is it's ability to create panoramic pictures. However, I noticed that sometimes the pictures didn't quite line up right. After talking to my brother-in-law about this I found out that the best panoramic pictures are created when the camera is rotated on it's axis. Perfect, this sounds like an opportunity for me to make a fixture! I've also been looking for a project to use 3D printing, so I think this will be a good opportunity to try it out.
Step 1: Find a CAD model of the Samsung Galaxy S3
The first step is to acquire a model of your phone. You can, of course, model it yourself in your favorite CAD software. However, there is a pretty good chance someone has already created a model if you have a popular phone. I found a nice model of the S3 on the GrabCAD
Step 2: Start Designing
It's time to import the model of the phone to your CAD software and start designing. I used Solidworks, but there are many other products out there such as FreeCAD, AutoCAD 123D, Google Sketchup, and Blender just to name a few.
I'll apologize right now for the vagueness of this step. It is time to let your creativity flow!
The goal of my design was to hold the phone in a stable position while allowing it to rotate around a vertical axis that goes through the camera. I also wanted to be able to mount it on a tri-pod in addition to being using it on a tabletop.
Since this was my first 3D printing project I wanted to have a little fun and incorporate some of the freedom of design that you are given with 3D printing. I typically design machine parts that are milled on a CNC and have to obey the design laws that go along with that method of manufacturing.
