GoPro-style bike light mount under computer
An under-computer light mount hangs a front light beneath an out-front GPS mount using the standard GoPro three-prong interface, freeing bar space and lowering the beam. The mount has three 3 mm thick fins spaced with 3.2 mm gaps and a 5.2 mm hole for the thumbscrew, a 40 mm drop arm 8 mm thick, and a second GoPro tab or a 22 mm cylinder at the end for the light. Printing the arm upright with 100 percent infill in PETG keeps it rigid on rough tarmac.

Fit notes
SpeakCAD builds the arm length, drop and light interface around your particular computer mount and light, so the beam clears the tyre and the buttons remain reachable. Change the angle or add a camera tab in the chat, and preview in the browser.

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.
