Rear Light Mount for Standard and Fatbike Rear Pannier Rack

thingiverse

This design was tailored specifically for fat bike rear racks like the Axiom Fatliner, however, it can still be adapted for use with other types of racks, although the mounting holes may not align perfectly with each unique rack. I've personally used this on a standard rack secured with zip ties and found it to be relatively easy to drill additional holes as needed to accommodate whatever type of rack you're working with. The curved portion features flat sections that help maintain your light at desired angles.
