Tripod phone clamp with quarter-inch thread
A phone clamp turns any tripod into a video rig, and a printed one can be sized for a phone in a thick case that commercial clamps refuse. The clamp has two jaws with 6 mm rubber-pad recesses, a body that opens from 65 to 90 mm using a slotted slider and an M4 thumbscrew, and a 6.4 mm hole with a hex nut pocket for the 1/4-20 tripod stud. Jaws 12 mm deep hold the phone without covering the buttons, and PETG resists the constant spring tension. Open the ready-made model free, resize it on your phone or computer, then download a print-ready STL, 3MF or G-code sliced for your printer, free.Opening the ready-made model and downloading it as STL or 3MF are free, no card; AI changes use credits, from Maker at $7.99 a month.No printer?

Example prompt
Create a phone tripod clamp with a fixed jaw and a sliding jaw adjustable from 65 to 90 mm via a 6 mm slot and M4 thumbscrew, 12 mm deep jaws with pad recesses, and a 6.4 mm hole with an 11 mm hex nut pocket for a 1/4-20 stud.
Fit notes
Rather than praying a download fits your specific case, give SpeakCAD your phone's width and thickness and get a clamp built around it. Add a cold shoe on top for a mic or a landscape lock in the chat, and preview the model before downloading.

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.
