I wanted to create a unique, customizable and flexible case for my brand new iPhone 8. I used Dynamo, the open-source visual programming system from Autodesk and its experimental system for creating generative designs: Project Fractal. The result is this cool Voronoi pattern that simulates the nightmare of every iPhone user: a cracked screen. If you want to play around with the design and download your own STL, see the “customizer” here. I used SainSmart TPU – which has a nice balance of flexibility and strength. The next step is to add some more sizes and experiment with how to smooth out the rough edges on the final print.
