Double Helix DNA (no supports!)

I recently bought a new printer, and I wanted to test my CAD skills as well as the printer's abilities. This design definitely did both! It's a difficult model to print, but it looks awesome when it's finished. 

Recommended Print Settings:

(At 100% scale)

Resolution: .15-.2mm

Infill: 20%

Supports: No

Wall count: 2

You may need to enable “Z-hop when retracted” if the nozzle is snagging on the towers during jumps.
