Measuring volume of 3D object through z-stack

Hi all. I have a z-stack of images of a 3d object (cell with membrane marker). For each individual slice I can manually outline the cell. Does a plugin already exist that can interpolate between the 2D outlines to estimate volume of the 3D object? If not, is there already a method that can estimate volume? I can start something from scratch but I assumed someone might have done something similar already. Thanks.

Edit: I am using ImageJ/FIJI for this

You could use Cavalieri’s principle to estimate the volume of the object.
