I used Autodesk inventor to design a phone stand for a key chain. I used a laser printer to print the final product which could hold my iPhone 5 with the case on it. Project was inspired by
Easy DIY phone holder keychain.

Step 1: Design
I first used design software to come up with a basic design to hold up the phone without the case with a with all around of .3in
Step 2: Prototype
I decided that I would like to make a design in which I did not have to take my case off to use it. I increased the width of the slots to .5in
Step 3: Prototype #2
I printed the design with .5 in slots which ended up being to large to hold my phone with the case. I then got a dial caliper and measured the width of the case and estimated it to be around .4 in I then revised the original design and added rounded edges on the points.
Step 4: Prototype #3
I printed out a version that held the phone with the case firmly. it had two slots where the phone could be held but the one didn't serve much of a purpose so I decided to take it off and remove it from the design. The design also would be able to use a keychain ring
Step 5: Final Product and Product Evolution
I then edited the design files so there was one slot to hold the phone, I also changed the location of the keychain hole so that a key ring would fit trough and be able to hold it without breaking.
