For my final capstone project, I made a 3D-modeled phone case, inspired from the spikes of the hedgehogs.
I wanted to make a phone case that help people to stop using their phone, and end product did fulfill my initial expectation.
The back is made of movable spikes with a mechanism inspired by lego.
And this is a blown up shot on the side.
I like your idea about making a phone case. What material do you plan on using? How would you manufacture it?
