What a iphone 17 pro magsafe bike stem mount is
An out-front bicycle mount that holds an iPhone 17 Pro (about 150 × 72 × 8.8 mm) on a MagSafe ring so the camera bar clears the stem. The head is a 56 mm MagSafe-aligned disc 3.2 mm thick with six 6 × 2 mm magnet pockets, a 1 mm lip that stops the phone sliding off under braking, and a 22.2 mm stem clamp with 0.3 mm shim slots for 31.8 mm bars via a printed insert. The arm is 80 mm long, 18 mm wide and 8 mm thick, printed on its side in PETG with 2.4 mm walls so the clamp threads stay crisp.
A stem mount sold for last year's iPhone sits the camera bar on the arm and blocks the ultrawide. In SpeakCAD you type the phone thickness and bar diameter you measured, preview the mount in the browser at no cost, ask for a GoPro adapter under the disc in the chat, then download the STL.
