MagSafe phone holder for shopping cart handle
A hook that drops over a 25 to 30 mm shopping cart handle and presents a MagSafe magnet ring so an iPhone 15, 16 or any Qi2 phone hangs from its magnets while you follow the list. The 60 mm round face has a 56.5 mm pocket 1.8 mm deep for a stick-on MagSafe ring such as an ESR HaloLock or a Belkin adapter ring, angled 15 degrees toward you. The hook is 25 mm wide with a 32 mm inside radius so it fits most cart handles, walls are 3 mm, and it prints on its side in one piece.
Because the ring pocket and hook radius are both driven by what you own, a downloaded file rarely fits. In SpeakCAD you give the ring diameter and the handle size, preview the holder free in the browser, refine the angle in the chat, then download the STL for PETG.
Design a shopping cart phone hook with a 25 mm wide hook of 32 mm inside diameter for the handle, joined to a 60 mm round face tilted 15 degrees containing a 56.5 mm diameter, 1.8 mm deep pocket for a stick-on MagSafe ring, 3 mm walls and a 2 mm retaining lip.
