Knog Blinder light to GoPro mount adapter
Knog Blinder and Plus lights strap around a handlebar with an integrated silicone band, which means they cannot use the GoPro mount under most out-front computer mounts. This adapter is a short dummy bar: a 22 mm diameter, 30 mm long cylinder with a 2 mm groove that the Knog band wraps and locks into, mounted on a two-finger GoPro fork (3 mm fingers, 3.2 mm gap, M5 hole). The cylinder is hollow with 2.5 mm walls to save filament and prints fingers-up in PETG without supports.

Example prompt
Design a bike light adapter consisting of a hollow 22 mm diameter, 30 mm long cylinder with 2.5 mm walls and a 2 mm deep strap groove, attached to a two-finger GoPro fork with 3 mm fingers, a 3.2 mm gap and a 5.2 mm hole.
Fit notes
A downloaded adapter is usually cut for one bar diameter and a different band length, so the light ends up loose or the band overstretched. Tell SpeakCAD your Knog model and the diameter the band grips best, preview the adapter in the browser, adjust the groove depth 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.
