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.
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 free in the browser.
Create a GoPro-style light mount with a three-fin upper connector, 3 mm fins and 3.2 mm gaps with a 5.2 mm through hole, a 40 mm drop arm 8 mm thick, and a lower two-fin connector rotated 90 degrees with the same hole size.
