Peak Design mobile SlimLink to 1/4-20 tripod adapter
A tripod adapter for Peak Design Everyday cases and Universal adapters that reproduces the square SlimLink mounting boss and adds a 1/4-20 socket underneath for tripods, gimbals and clamp arms. The boss is about 24 mm square and 3 mm tall with rounded corners and four pockets for 6 x 2 mm disc magnets so the phone snaps on by magnet, while two shallow side slots let you add a printed or metal locking tab if you want a mechanical hold. The 40 mm base is 8 mm thick with a 1/4-20 pocket for a brass insert, and prints flat.
Peak Design uses precise recess dimensions, so a downloaded boss that is half a millimetre off will not sit flush. In SpeakCAD you give the measurements from your case, preview the adapter free in the browser, refine the boss or magnet pockets in the chat, then download the STL.
