The file 'DNA 3D Printer Model' is (stl) file type, size is 575.6KB.
This dna segment has 3 base pairs. I made the top and bottom flat so you can print multiple and put them together. The parts of the dna are labeled in one of the images above. The one I made is two put together. This needs no additional supports.
