Snowflake Box

I am still working on this model. I want to put a top bar on the box and resolve the print quality issues.

Any suggestions on removing the stringing.

It was printed on a RigidBot 10^3 using a .4mm nozzle in PLA (from RigidBot) at 210c on a 70c bed. The printing room is heated to about 14c. ?

This was made using Imaginary Spaces.
The Gcode is from Cura 14.09, retraction speed 40mm/s & distance 5.5mm.
