Quad Lock to 1/4-20 tripod adapter plate
A disc that screws onto any tripod, gimbal or selfie stick with a standard 1/4-20 thread and carries a Quad Lock style twist recess, so a phone in a Quad Lock case locks on with a quarter turn for filming. The recess copies the four-lug case pattern, about 37 mm across and 4 mm deep, with a printed friction bump holding the twist, and the underside has a 6.35 mm threaded boss modelled as a 1/4-20 profile or a pocket for a brass insert nut. The disc is 45 mm across and 8 mm thick and prints flat.

Fit notes
Tripod adapters from other printers are drawn for one case revision and one printer's tolerances. In SpeakCAD you describe your case lugs and whether you want printed threads or an insert, preview the plate in the browser, refine the fit in the chat, then download the STL.

A shared STL is modelled for someone else's measurements. Here you open the ready-made model free, change it to your measurements in the viewer, then download a file sized for the part you actually own, free as STL or 3MF.
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.
