Lidl's Livarno Lux Solar Garden Globe:
The extension tube (size the same as the original one), spike and an alternative spike to use the lamp without the extension tube.

Broke a spike so while designing one I decided to do also the extension in case it was useful for someone.
Then had the idea of making an alternative spike for those that wish to place these lights the closest to the ground possible (without the extension tube).
If you wish different height simply scale the tube Z axis on the slicer while keeping X and Y untouched.

Feel free to remix, change, whatever and share...
