Coral Rock Thing

Was experimenting with Blender Geometry Nodes and decided I liked the model so I printed one for my fish tank.

The print requires supports.

The object is fairly large (~180x190mm), so you could print it at 80% scale or smaller, depending on the desired size. At 100% scale it took quite a while, but it printed well.

The attached STL file is the raw object. To get a printable model use your slicer to cut the bottom off (I cut it at ~65mm). You can rotate it prior to cutting to get a different variation on the model. The attached 3MF is cut to make the bottom flat.

Printed with SUNLU Rainbow Silk PLA+ at 0.3mm layer height.
