Wingee bag hook addon

I got a new bicycle (ebike) with a rigid fender/ bag mount from [wingee](http://wingee.bike). I also have some Ortlieb bicycle bags with a hook at the bottom side of the bag to secure it. But sadly the wingee fender/ bag holder doesn't have the needed hook holder for these ortlieb bags, which is the point of this part.

Just unscrew the hex screw and clip this part on the right wingee arm and slide it down until the holes align and install the hex screw again and you are done.

This is the part for the right side, there is no version for the left side (yet)

I have drawn this part with Freecad 0.16 and the freecad file is also in the download section available.
