The Swiss robotics engineer behind a commercial case that adds USB-C to Lightning iPhones has now built a reverse version: A case that adds a fully functional Lightning port to the iPhone 17 Pro.
Ken Pillonel describes the project as a tongue-in-cheek response to reader requests, and says he has no plans to sell it. “It’s part hack, part mod, and one of the most cursed things I’ve ever built,” he wrote in the video description, “Be careful what you wish for.”
The build involved designing custom PCBs for precise connector placement, 3D printing a flexible TPU case on a Formlabs SLS printer, and fabricating a magnet installation jig on a Prusa printer. The finished case is slim and flexible, with MagSafe alignment and a snap-fit assembly.
Pillonel set himself a deadline of April Fools’ Day to complete the prototype. The project builds on his long history of connector-swapping work, which includes adding USB-C to an iPhone X in 2021 and a USB-C conversion kit for AirPods Max in 2024.
