About once a year, I design and daily drive a new phone case to test out new manufacturing methods and explore fun mechanisms.
The design goals are to create a slim phone case that can withstand hard drops and store three credit cards. These are competing goals which make for a surprisingly difficult design challenge
V1 (2022) V2 (2023) V3 (2024) V4 (2024) V5 (2025)
These are the actual phone cases after being used and abused for a year. Some have worn much better than others.
