Seatpost soda bottle fender for 27.2mm post

remove 27.2mm post, press fit fender holder on and secure with 5mm bolts, just tap your own thread with bolt into the plastic. insert soda bottle, and go for a ride in the rain...Angled to suit my 29er...Load a cut in half coke / soda bottle into the rear thread...second pic shows the thread. Still might have to spin the thread around so bottle finishes facing down...I will test print and fix when I have time..
