This 3D model represents the nucleosome based on the 3C1B X-ray crystallography structure. It illustrates the organization of DNA wrapped around the histone protein core, the fundamental unit of chromatin in eukaryotic cells (in this case a frog). The model has been optimized for reliable 3D printing while preserving the overall structural features. It is ideal for teaching molecular biology, genetics, and structural biology concepts. This model is intended for educational, visual demonstration, and scientific outreach purposes.
Coloring:
DNA: white
Histone H2A: blue
Histone H2B: green
Histone H3: red
Histone H4: yellow
Print information:
Printer: Prusa MK4S
Supports required: Yes !!! Organic!!!
Layer height: min. 0.2 mm recommended for nice quality
Print scale: mind. 150 % recommended
Print time for huge 180% scale with 0.2 mm layer hight: around 46h
Filament type: PLA

USE organic supports !!! --> won't work otherwise
CAREFULLY remove the supports
Enjoy putting the histones and the DNA together with super glue oder by hand melting some filament with a gas-lighter
