Magnetic balls lamp base

I've got this magnetic balls lamp manufactured by Grundig (but it's sold as well by a lot of other chinese brands), that's very unstable and prone to tipping because it's very light and has a small footprint. Mine is the smaller model, with the 55mm diameter base.
I designed this support to add some weight and extend the footprint and avoid it to tip.

Printed on Ender 5 Pro with PLA, no supports needed.
Sliced in Cura with "standard quality" setting (0.2mm).
