Usb cube security

I designed this because my mother is in a nursing home and her phone charger and cable keep disappearing. This is designed for the 1" apple cube charger and clones. It will only work with the outlet that has the ground close to the cover plate mounting screw,

To use remove the cover plate screw and use a 6-32 by 3/4" screw

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/lLBXkJmpOka
