These are electostatic potential maps for molecules that regulate the intrinsic cell death pathway and a couple of others for fun. All structures were sourced from https://www.rcsb.org/. The 4 character code in the filename is the PDB acension number. The structures were loaded into pymol (https://pymol.org/2/) and converted to electrostatic maps. These were then exported as STL files, loaded into blender to be cleaned up. I printed them on a Creality Ender S1 using default settings. A lot support is needed so you'll have an hour or two of ASMR fun removing it (or tedium depending on your temperament). 

I apologise for errors, omissions and inaccuracies, I'm not a molecular biologist let alone a structural biologist.

The MCL1 structure seems to be at a different scale to the others. I don't know why that is.
