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.

Example prompt
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.
Fit notes
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 in the browser, refine the angle in the chat, then download the STL for PETG.

Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
