There are several DNA double helix molecule models available on Thingiverse. The model I 3D printed was posted by user Hello18. The license this user put their model under is the least restrictive Creative Commons license (CC-BY).

The entire print took around three hours to complete with the same settings I use for other prints. A little over 8 meters of 1.75 mm filament was consumed.

There were no recommended print settings for the model on Thingiverse. I was able to get by with just a skirt and 20% infill. If I had to print this again I would probably use a brim and at least 60% infill.

This wasn't my first attempt at printing this model. I tried earlier using the sample Tronxy filament that came with the 3D printer but its brittle characteristic was a problem. During the second attempt using Hatchbox red filament the nozzle got clogged after printing the base. The nozzle just needed to be cleaned.

It turned out to be worth the effort. It's a nice model.

Can I just ask, are the prints paintable and if so, what paints, undercoats, primers etc would you recommend to use?
Having just seen there is a 3D print community, I will join and have a trawl through.
EDIT Since reading this, I went to have a look at thingiverse.com Amazing the stuff......and a lot of it so useful and ingenious. Totally awesome. Now if someone could invent a way to 3D Print more hours in a day...
Great post :-)
I haven't done any painting yet but here is a beginner's guide to painting PLA and ABS prints on all3dp.com.
Thank you for the taking the time to drop the link. So much potential for model makers with 3D printing but the finishing would be important.
That double helix model is super cool looking, I like it in the red like that :)
I just printed a dodecahedron successfully for the first time, and also a print in place bearing that came out pretty perfect :)
I'll probably make a post about it tomorrow, pretty exhausted right now , been a long day.
Really great to see you making some progress, keep it up! :)
In case you are interested, this is a fun one to try to print.
(10 mm brim worked great) https://www.thingiverse.com/thing:3021038
Eventually I will print something like that but not from the link you provided. My preference is as least restrictive license as possible so more likely this Pentakis dodecahedron under a CC-BY license.
I understand technically the Thingiverse user (mathgrrl) can put that under a CC BY-NC-SA license but I also question how legally enforceable such a claim to that mathematical shape can be. What original expression did mathgrrl add that I can't detect? In the United States we don't really abide by the "sweat of the brow" doctrine.
"The United States rejected this doctrine in the 1991 United States Supreme Court case Feist Publications v. Rural Telephone Service;[4] until then it had been upheld in a number of US copyright cases.[5][6]
Under the Feist ruling in the US, mere collections of facts are considered unoriginal and thus not protected by copyright, no matter how much work went into collating them. The arrangement and presentation of a collection may be original, but not if it is "simple and obvious" such as a list in alphabetical or chronological order."
Not much if I'm interpreting this correctly.
But I think it comes down to perception of what people think is ok and what is not ok.
In other words, I sense disdain from you that she would use the CC BY-NC-SA license.
And that disdain echoes with me, I get it.
I didn't even look at the licensing stuff yet again.. I should probably be more vigilant with this.
Not disdain since I accept the premise the Thingiverse user can place that license on the design. I question whether that was an appropriate choice.
I can do the Sherlockian inductive reasoning thing and postulate that "mathgrrl" resides in North America since "math" rather than "maths" is the preferred noun for most English speakers in North America. Using mathgrrl's profile on Thingiverse I can confirm the postulate and narrow mathgrrl's residence likely to be somewhere in Virginia.
The license a designer puts their design under shouldn't seem arbitrary. If I print the design from your link my choices and possible uses are more limited by license than the design I linked to even though both are essentially the same design. If mathgrrl added something original then I would understand why that file for download from Thingiverse has more restrictions under its license.
