I don't have room to mount a light on my bicycle's handlebars (there's a pack in the way). But my bike has braze on attachment points for low-rider racks on the front forks. I designed this little part to fit on the front fork (it will work on either side). The outside diameter is the same as my handlebars, so the clip that holds my light in place fits perfectly. I suppose you could use it to mount any gadget you don't have room for on your handlebars (Go-Pro anyone?)

The original design was done in Rhino.
