These models provide the basics for constructing a DNA double helix.
Each nucleotide requires: 1 Backbone and 1 Base (G,C,T, or A)
Each base pair requires: 2 nucleotides (above) and 2 (A-T) or 3 (G-C) hydrogen bonds (Hbond).
All the base and backbone models have keyed cut-aways to help orient the models during assembly.
Remember when assembling that the strands run opposite directions!
Print instructions
You will need supports. Unfortunately, out of the box PrusaSlicer is terrible at printing spheres. I recommend using Cura for this or use SuperSlicer and decrease the support XY distance to 0.16 and use concentric interface layers.
