Quad Lock to Peak Design SlimLink adapter plate
An adapter puck with a Quad Lock style four-lug pattern on one face and a Peak Design SlimLink style square boss on the other, so a phone in a Peak Design Everyday case can use Quad Lock bike and car mounts you already own. The lug side is about 37 mm across and 4 mm tall to twist into the mount, and the SlimLink boss copies the square recess in the case with pockets for four 6 x 2 mm disc magnets glued in for retention. The disc is 6 mm thick, prints flat, and a 0.2 mm clearance keeps the twist firm.

Example prompt
Create a 45 mm diameter, 6 mm thick adapter disc with a Quad Lock style four-lug boss 37 mm across and 4 mm tall on one face, and a Peak Design SlimLink style square boss 24 x 24 x 3 mm on the other with four 6 x 2 mm magnet pockets and 0.2 mm clearance.
Fit notes
Both interfaces have tight tolerances and both brands have revised them, so a downloaded adapter may fit neither of yours. In SpeakCAD you type the measurements from your own case and mount, preview the adapter in the browser, refine the lug fit in the chat, then download the STL.

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.
