Instead of a 3d printed stone, I designed an insert tat can be inserted into a stone and then set in e.g. concrete.

Instead of using a fully 3D-printed stone, this model can be embedded into a real stone by placing it in a drilled hole and securing it with concrete or another suitable material.
The outer diameter of the zylinder, that is inserted, is 23mm.Since the fixing matierial requires some clearance, the hole should provide a loose fit.
I chose to drill a 32mm hole. To achieve this, I first drilled an 8 mm pilot hole with a small hammer drill (to reduce the risk of splitting the stone), then stepped up to 24mm with a larger hammer drill and finally a 32mm drill, all the while cooling the drill and the stone with a garden hose.
I think granite is well suited for that because it does not split as easily.
In the photo I used the model with a 30mm collar, but I also included one with a 40mm collar one, as it would hide the fixing material better.
I printed the insert with .24mm layer height to save time, but it does not really matter since only the bottom layer will be visible. Supports are not necessary.
