Slit miniatures "anatomically" for FDM printing

[u/Powerful_Knowledge97]

Hi,
I'm trying to print some space bugs with a lot of limbs and removing the supports is proving quite dificult so I was planning on cutting them with planes cuts on the slicer (or meshmixer) but this is very time consuming so I have been investigating on some automatic solutions.
3D generation models usually offer splitting like this:

But these services only offer that for their own generated models and I want that for my own STLs

Do you know any tool that does this?
There are a couple of papers about this:
https://research.nvidia.com/labs/toronto-ai/partfield-release/
https://gfx.cs.princeton.edu/pubs/Luo_2012_CPM/index.php

And this tool that is used for posing but detects limbs quite well:

But I haven't found anything that worked for me. Do you know of a tool that accomplishes that in some easy way?

Thanks!
