Kryptonite mini xtra safety bike lock

thingiverse

What makes a lock safe? It´s the time the thief needs to open it, the more time he needs the safer the lock will be. So I designed this thing you pull it over the keyhole so the thief can´t pick it. Bevor he could pick the lock he must remove the xtra lock. Most thiefs (i think :)) won´t carry big extra tools if they are specialized in picking that kind of locks. Because the pipe fits tight over the lock it is very hard to brake. Printing with 100% infill is recommended ;)
