Cold shoe mount adapter for camera
A cold shoe adapter lets you bolt a microphone, light or monitor onto a camera cage or tripod that only offers a 1/4 inch thread. The shoe channel is 18.6 mm wide with 1.5 mm rails and a 4.5 mm gap under them, a 20 mm long body 8 mm tall, and a 6.4 mm through hole for the 1/4-20 bolt with a 12 mm hex recess for a nylon lock nut. Printing it flat in PETG keeps the rails dimensionally stable and stiff enough for a 300 g shotgun mic.

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.
