i’ve revisited the `collider` method using the part centrelines. this is much faster and works for more parts than the `rigidbody` method. with the zombie solver i’m getting a valid solution for 100 parts in under 30 seconds. It’s not always meeting all the goals. i’ll keep tweaking

here are 70 nodes almost fitting in the Anycubic photon mono x

I’ve found that adjusting vertical load strength in relation to the other goals has a large impact on stability. lower gravity is usually better. the actual magnitude of the strengths is irrelevant.

This requires the same rhino file above and
