3D model description

The geode is mounted by inserting (forcing) rods into "cones" of junctions, which is simpler than the gluing method I previously proposed.

You need 60 short stems, 60 long stems, 12 5-branch "cones" and 30 6-branch "cones". We make 12 pyramids with 5 (short) branches and 5 long base stems linked together according to the attached drawing (or by using the photo as a guide: short white stems, red for the long ones).

The files of the rods are of type 3mf so we can build geodes of different sizes; to do so, it is enough to lengthen the cylinders of the rods by the same factor without changing the diameters of the spheres of the ends). 3DBuilder makes it easy to do this operation.

The files of the "cones" are of type stl.

With the supplied files we obtain a geode of about 30 cm.

You can easily fit 30 cones or 26 rods on a 20x20cm printing plate.

With a small adaptation, it can be made into a hanging lamp.

3D printing settings

PLA 210Β° without support for "cones", with support for rods.
