Double Helix Pencil Holder

thingiverse

A DNA-inspired pencil holder constructed from a double helix design. The helix structure is reinforced by a wire frame that maintains its stability and functionality as a pencil holder. Details of the design can be found in the OpenSCAD code. Print Settings: Printer Brand: MakerBot Printer Model: MakerBot Replicator (5th Generation) Rafts: Not Required Supports: None Needed Resolution: 0.3 mm Note: The pencil holder's design is based on the B form of DNA, with a scale factor that makes 2.3 mm on the model equivalent to an Angstrom unit. The smaller groove, measuring 13 Angstroms, corresponds to a vertical distance of 30 mm between strands, while the larger groove, measuring 21 Angstroms, represents a vertical distance of 48 mm. The diameter of the helices, equal to 20 Angstroms, is approximately 46 mm on the model.
