I want to 3D print a model of a vertebra for my brother but I wanted to spice it up and print it in a voronoi style. I'm aware that this can be done by adding wiremesh and sub surf modifiers.

The problem I have with this is that the model is then a shell of what it was, and I'd rather it looked filled-in like bone matrix.

How can I make a 3D voronoi of the model I have with randomly generated internal geometry.

As a side note, the wiremesh modifier ignores any internal geometry - I did try manually adding some and wiremeshing it.

Here is an example image of what I mean:

Example of what I want

Any help would be very much appreciated!

Something can be done with Cell Fracture addon, Merge by Distance, Delete by Limited Disolve, Delete Only Faces ... you end up with just edges ... ad Skin, Remesh, Smooth modifier in this order.

enter image description here

If Skin modifier ignores some edges, go to Edit mode and select some of this ignored vertex and Mark as Root.

Anyway for such model like your (Dear with this cell size) it could be a calculation killer :) I'm posting it just as a tip before some geo-nodes guru comes to help here :)
