A model of DNA, A is blue T is red C is yellow G is green The deoxyribose sugars are black The phosphate groups are white The hydrogen bonds are the grey lines in between the bases Each segment is 2cm tall, I printed 12, so my model is approximately 25cm tall (1cm base) The base is a round wooden piece I spray painted white, made holes for the bottom two cylinders, and epoxied the model into Print Settings Rafts: No Supports: No Resolution: I printed mine at 0.3 Infill: 40% Notes: White PLA filament preferred so you can paint on it Post-Printing Acrylic paints work best on PLA Paint the square parts black, these are the deoxyribose sugars Keep the cylindrical parts white, these are the phosphate groups Paint each rung 2 colors, corresponding with the bases A, T, C and G Paint a grey line in between the bases, this symbolizes the hydrogen bond How I Designed This I made this using mainly the rotate extrude function in openscad You can edit it to fit your parameters
