The original cover for the M115X-series (see here) Master Lock® brand padlock can get damaged over time or can become sticky as some rubbers of the era tend to do. This replacement cover can be used to replace the original and provide continued protection from weather and other environmental factors.
This design uses concepts from the original OEM design but is not compatible with any part of the original. It uses a 3-part construction including the top, bottom, and a bridge between the shackle for easy assembly. It has locking nubs to ensure the top/bottom remain assembled. It does not include a cover for the core keyway like the OEM one and is instead open.
You'll almost surely need to print this with TPU (rubber). I cannot speak for its longevity or UV resistance when used outdoors.
