3D Printing a DNA Model

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.
