Was that a trailer for the entire trilogy? Cause holy shit that is a lot to pack into 90 minutes

I have no clue about that. I only recently stumbled across the orca setting while waging my own battle against excessively aggressive supports.

In Orca slicer, if you use tree supports and hybrid, an option appears (advanced must be enabled) for something like “Essential supports only”. It is so much better than spending all that time adding or blocking supports.

Print with larger holes, but then use multiple layers. Like Russian nesting dolls, but each “doll” would be rotated very slightly.
Also, try slots in opposite directions. Horizontal slots nested inside vertical slots would effectively create a mesh.
Flat panel inserts could be printed easily and then slid into a circular holder.
