When testing the viability of the laser cut phone holder, most of the early models were cut and folded by hand. This allowed for more rapid exploration and alterations.

This helped to inform future iterations, building upon the strengths of successful versions and redesigning elements that weren't obvious, so that the process could be as intuitive as possible.
