Surly "Nice Rack" Light Bracket

This is my first model built in Blender and is used to mount a standard handlebar light under the rack.

I'm happy with the result, but depending on the light you want to mount it may be necessary to lower the mount point for extra clearance under the horizontal bar (see images).

I didn't print this myself, but I found that the result should be slightly flexible for best results, ABS with a 20% infill seems to work well.
