Garden Solar Panel Mount

Decided to design and print proper mount for the solar panel for Christmas lights that I bought last year. The original one was short tube pushed in the ground. Not the best solution as it was mostly covered in shadows of surrounding plants.Diameter is 18.46mm and length of the shaft 20mm. It is snug fit - should withstand wind.Printed in PETG. It should last as the panel is not heavy at all.
