12 points, attached to a dodecahedron frame via M12 threaded rod.

I printed the rod at 95% size, for me it made it easier to assemble. Take care when screwing together, the rod can brake easily. Alternatively just gluing the parts together will work.

Made using FreeCAD, file included.

** UPDATE 2nd December 2024 **

Added a point that has a hole in the end, print one of these and then you can thread through it to hang it above your Christmas tree.
