How to create compartment to existing 3d File

Hi maker’s,
I need help to add a threaded compartment to an existing 3d file.

For example a esculper of a cat or dog and on the bottom add a screw-on lid to stage stuff inside.

It´s possible ?

Sure it is.

Create the thread/compartment that you want (as a male thread) and import it as a “Negative Part”. Alternatively you use the Boolean mesh to subtract the thread/compartment from the model.

I can create with the bambu lab slicer ?

The threaded geometry will need to be created with something outside of Bambu studio. The compartment can be created within Bambu Studio using a “Negative Part”.
