DNA Gadget - A double helix in a double helix
thingiverse
Update/Warning: 10/6/2016 - I can't get this STL file/design to print. It looks like my DNA pencil holder can also double as a strange DNA in a DNA helix gadget or fidget thingy. If you print one these STL files you will have two interlocked DNA models. Files: DNA_Helix_Pencil_Holder_Remixed_two_in_one01.stl is very tall 215mm and needs a larger printer to handle. DNA_Helix_Pencil_Holder_Remixed_two_in_one01_68percent_scaled.stl is scaled down to below 150mm height. Disclaimer: I have yet to print this and I'm worried about bridging at the top. I'll re-post after I print. I was able to make this item by duplicating the STL file from the original pencil holder helix design in the slicer software and rotating one copy on top of the other.
