I used PLA, with standard print height (.02 mm). I did 100% infill because anything less made the branches break a little too easily. I raised the temperature to 240C, and kept the printing speed at 90m/s, but lowered the movement speed to 125m/s. I scaled the print to be 2.25in high and printed using a raft.
If I had a do-over, I'd probably decrease the layer height to .15 or .1, just because the curves didn't come out quite as smooth as they could have.
Hope that helps!
Would you mind sharing the settings you used to print it? PLA or ABS? Layer height? infill? speed?
