Thule RoundTrip Axle adapter

I designed this axle adapter for the Thule Roundtrip as I have a soft carbon fork and didn't like the hard-mount alloy adapters (they have a tendency to scratch frames if you're not careful!). suits 12mm axle, but can be scaled internally either using BambuStudio and negative shape inserts, or adjusted accordingly. The small ridges inside and outside the mount are designed for o-rings that should add a bit of "give" to the mount for your frame in transport. Happy biking (and travelling!)
