Rear Fender Mount for Cannondale Topstone Carbon / SKS Velo 42 Urban

Two part rear fender mount for Cannondale Topstone Carbon. 

The upper screw mount should be quite universal for different fenders, while the lower clamping mount is specific to the SKS Velo 42 Urban Fender that I reused from an old bike. 

FreeCAD 1.0 design file attached, feel free to remix for other bikes or fenders.

Printed in PETG on Bambulab A1 with 0.2 strength profile. The lower mount is printed with 10 bottom layers to get a solid flat part.

The mounts use the M5 flathead screws from the bike and one M5x10 flathead screw with a self locking hex nut for the fender.
