DNA Assembly

thingiverse

The modeling process for this structure is outlined in my book titled "Modeling in SketchUp for 3D Printing". Essentially, it's a twisted ladder with sides and rungs. To assemble it, first print two side pieces and four rungs, using different colors if your printer has dual extruders. Attach the rungs to one of the sides, then securely fasten the second side from the top downwards. For multiple layers, repeat the process with more sets of rungs and sides. Don't forget to print two support pieces if you want your DNA ladder to stand upright.
