I am picky - I don’t like seeing bike headlights stick out the front of my handlebars, so I made an adapter that runs it above or below the stem, the stem being a Pro Vibe model. The stem is pretty wacky, so I first had to figure out the profile before I could work on the clamp...for which there were multiple iterations. I reverse engineered a KNOG light clamp o-ring attachment for use with this 3D printed clamp.
