Dna Helix 3d Model. To twist your model into a helix start by grabbing onto each end with your hands and slowly twisting your hands in opposite directions. If one wants to animate the strand adding a basic shape key to the path would allow perfect animation as the geometry will follow the path.

This design will not need any supports or rafting because the printer at least the makerbot can stretch a piece of plastic over an area multiple times to create the cross.
The 3d double helix human dna model by the human origin project dna of all life on earth adherers to a double stranded double helix model like two ladders spun around each other. Twist the strands into a helix to finish your dna model. Based on available data from x ray diffraction patterns and 3d conceptualization through model building watson and crick proposed that dna is a double helix a twisted ladder with two phosphate based backbones and runged nucleotides that pair. I have printed this design on the makerbot replicator 2 with no supports or rafting and it worked perfectly.
