MagSafe charger puck to 1/4-20 tripod mount adapter
A holder that turns an Apple MagSafe charger puck (56 mm diameter, about 5.5 mm thick) into a magnetic tripod head, so an iPhone 16 Pro snaps onto any tripod or selfie stick and charges while you film. The puck presses into a 56.4 mm pocket with a 1.2 mm lip, the cable leaves through a 4 mm side slot, and the 12 mm thick body has a 1/4-20 pocket for a brass insert or printed thread underneath. It prints flat with 2.5 mm walls.
Tripod mounts downloaded from a general site rarely combine the puck fit and the thread depth correctly, and a loose puck will tumble off with the phone attached. In SpeakCAD you describe your puck brand, whether you want an insert, and the phone weight, preview the adapter free in the browser, refine the lip in the chat, then download the STL.
Design a 62 mm diameter, 12 mm thick tripod adapter with a 56.4 mm diameter, 5.5 mm deep pocket for a MagSafe charger puck, a 1.2 mm retaining lip, a 4 mm side cable slot, a 1/4-20 brass insert pocket 6 mm deep centred on the underside and 2.5 mm walls.
