I designed this mount for a friend and co-worker that wanted to be able to mount a headlight on her Trek Speed Concept for early morning rides. It clamps around the aero bar extension and uses zip ties to hold it in place. You'll need to buy a K-edge insert to hold a Garmin device (about $5) and (2) M3 x 0.5mm nuts to secure the insert. I decided to use the insert instead of just printing the mount because it allows the insert to be turned 90°
for different device configurations. I've also found the insert makes a much smoother interface than a printed mount. On the bottom of the clamp is a Blendr mount that will allow her to use her Ion headlight or other GoPro style accesories.
