GoKawiilDesigner sells 3D-printable plans for retro brick phone that pairs via Bluetooth to iPhone
Cologne-based designer Kevin Noki built the ADHD ONE, a 3D-printed handset styled after 1980s brick phones, using a Raspberry Pi Pico, an FSC-BT1026C Bluetooth module, and a rechargeable battery. The device has no cellular radio of its own and instead connects via Bluetooth to an iPhone to make and receive calls. Noki is selling the design files, including STL parts, firmware, and manufacturing files, for €29.99 through his website.
