Customizable Double Helix

A double helix model representing DNA. My first Open SCAD model, and first contribution to Thingiverse. Happy to hear your feedback.

I had the best results customizing using a large size (like the defaults), and scaling in the slicer due to better corner rounding. The main pic is 80% scale, and 50% is more like a cute little Benchy sized print. Consider a color swap as it looks way better. Consider changing your top and bottom fill patterns to Octagram Spiral.

Depending on your filament, this can be a bit tough to print due to the curling of the leading edge of the arms overhang. You can see in the side-by-side picture that my Prusament PLA Azure Blue printed perfectly, but the Prusament PLA Oh My Gold printed with a ton of curling on the leading edge that messed up the bottom of the arms print. The gold looked so good I ran an experiment to figure out how to fix.

To fix the curling the 3 winning tricks seemed to be:
Slow things down to 10mm/s including travel above the base.
