Kryptonite U-lock rattle stopper

thingiverse

My trusty Kryptonite U-lock has been mounted inside my bike frame with the supplied bracket keeping it firmly in place. However, this lock has slipped out of its supporting bracket multiple times, landing on the floor while I'm cruising at full speed. Thankfully, it hasn't yet collided with a car or taken down another cyclist, but it's only a matter of time before that changes. To prevent further mishaps, I've created a simple stabilizing part that clamps to my seat tube and presses into the Kryptonite lock. This design was a breeze to create since the plastic cover on my lock is compromised where this part attaches - a problem newer locks won't face. I know this solution won't benefit anyone else, but Thingiverse makes it worth sharing. The slvs file (Solvespace) for this design is included for those who want to modify and improve it. Since I haven't put this part through its paces yet, I'm labeling it a work-in-progress for now.
