Key Hole Slot Plug Hook Bracket

This is a Key Hole bracket that holds my solar light. I am not allowed to drill holes on the outside of walls because I live in a rental.These allow me to hang the lights without drilling.

My first prints were PLA which are biodegradable and didnt last more than a week.
I used PETG for this. I am still experimenting as this hook is going to be used outdoor in the sun.
