Vertical support for solar lamp

I needed to put a lamp in a place to give some light. The issue is that the solar lamp I bought from Amazon wasn't providing a way to place the item in a vertical position, so I decided to design this vertical support.
Provide an addittional secure to prevent objects from falling if something breaks.
Comment to eventually make this support even better.
Use the PETG material rather than PLA, because it's better for outdoor use and for this purpose.

Edit 29/08/21: Actually I have been using it for 3 weeks without issues
