DNA Xoắn Kép - Thử Thách Cầu Nối

Test the bridging on your 3D printer with this DNA Double Helix model! The long bridges are in alternate directions so you can check your cooling in every direction.

I used the original version of this model to test my Positron, and I realized I've been printing this model for over a decade! 

There were a few small changes I've always wanted to make this model, so this is my updated version with no conical feature on the base and the made the mesh manifold.

Printed with Polymaker Polylite PLA in Black and White.

Original model by chylld on Thingiverse.
