How do you manage a three meter-long molecule if you are a 30 micron-wide cell? Lots of scaffolding proteins. This is a model of a histone complex, which is a complex of eight proteins that work together to organize DNA into a super-coiled structure, sort of like a fractal telephone cord.

I printed this in PLA, 0.1mm layer height at 50mm/s.
Print with support. I used KISSlicer's dense support function, with the support flow rate reduced to 70% by an external script. The support was still pretty hard, so you may be able to go even lower in the flow rate.
