I had trouble buying the Focus Adventure Rack for my bike, so I went to design my own version. Its tested on a Focus Atlas 6.8 Size 54 but should work with all the bigger sizes as well. Not suitable for wider tires than the 45 Riddler.
I made 3 versions:
I added two hollow cylinder since I printed in three parts anyway. This way I could add a 4mm aluminium rod for stability. Other than that, print recommendation is:
PETG, 4 perimeter, 15% gyroid infill
