Schlage SC1 LED Light House Key Replacement Holder

My light up LED key slowly fell apart, and I don't want to pay for a whole new key or spend time finding a place that has a working machine to cut it. Ideally, this would have been able to incorporate the LED, battery, and button. However, it fell apart slowly so I lost those parts a long time ago, so I don't have the ability to model a version of this that incorporates those parts.

If this one breaks on me as well then I will redesign it until it doesn't break. I will also try printing with a better material, but for my first run I am just using PLA Pro by Overture.
