Fasteners for Bicycle fender

The mount for the rear wing BBB, which uses a clamp type BFD-90, in which often breaks the threaded clamp. Now you can just print it. I used three types of plastic: ABS, HIPS, SBS. HIPS proved to be very fragile, the rest are normal. I spread two options: rounded and straight. I used a rounded, because so less plastic is twisting. Printed with support.
