Replacement sleeve for Kryptonite Keeper U-lock

thingiverse

This is a replacement for the sleeve that goes over the U-lock and clips into to the holder on your bike. It's designed for a 12mm diameter pipe and clip into a holder with a red button like on the picture. The other picture shows the replacement part (orange) next to the original part broken in an accident (black). Like the original part, the replacement has space for an M4 size screw and nut to tighten the sleeve around the pipe. Attached are two versions - one will fit very tightly around the pipe and may require a little bit of polishing with sandpaper to go in and out of the holder easily. The "loose fit" version should not require adjustments, but may be a bit loose. I recommend disabling supports for the gap at the bottom of the sleeve, as they may be difficult to remove and the gap is very small anyway.
