Insta360 X3 to GoPro finger mount adapter
The Insta360 X3 and X4 use a 1/4-20 tripod thread on the base, while bike, helmet and chest mounts use the GoPro three-finger interface. This adapter is a 20 mm square block with a captive 1/4-20 bolt or a heat-set 1/4-20 insert on top and a two-finger GoPro fork below (3 mm fingers, 3.2 mm gap, 5.2 mm hole), letting the camera clip onto any GoPro handlebar or seatpost mount. Total height is 22 mm to keep the camera low, walls are 4 mm around the insert and it prints fork-up in PETG.

Example prompt

Fit notes
A measured adapter keeps the heavy 180 g camera from rocking, which shows up as jitter in stabilised 360 footage. Describe the thread type and how far you want the camera offset in SpeakCAD, preview the adapter in the browser, adjust it 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.
