Transition Loam Shelf Guard/fender (carbon & aluminium V2 Sentinel )

Printed from with Flexafill 98A 
In my opinion/experience it should have vertical orientation with organic support touching only bottom side so the top side ( visible one ) will be smooth

As always with TPU, print slow. I went 20 mm/s. 

Glued with double side tape to the frame only at the top part so bottom can move with a chainstay.
