I had some problems with this print. Apparently the height is some mm too much for my replicator, so the tops are smeared. Reduce parameter second_height to avoid this if you build volume height is not 15 cm.
I printed with infill 10%, but that is too low, legs break too easy, so use more infill. The legs start to wobble easily due to the print head as the legs get higher, which reduces how nicely a printer can print this. Use a firmware with accelleration (eg for makerbot firmware 6.2 or 7), and not too high travel speed to reduce vibrations. It is possible to add a ring halfway of the height by using the fifth and sixt ring in the customizer, this would improve shaking during build, but I think it looks less nice :-)

Whatever you do, count on a 9 to 10 hours to build this.

To play around, in the customizer, use the following options:

sixth_height = 40
add_bottom = no
second_height = 150
second_skew = 0
third_skew = 0
fourth_extend = 1
first_skew = 0
fourth_skew = 0
fourth_radius = 30
sixth_radius = 0
bottom_height = 1
second_extend = 1
first_radius = 50
second_radius = 50
nrsticks = 18
scale_second_dir = 1
fourth_height = 1
third_extend = 1
build_plate_selector = 0
max_width = 145
r0 = 2
base_form = hexagon
build_plate_manual_y = 100
build_plate_manual_x = 100
first_height = 0
max_height = 150
fifth_radius = 0
sixth_skew = 90
fifth_skew = -27
third_radius = 60
sixth_extend = 5
fifth_extend = 2
first_extend = 1
fifth_height = 20
size = 3
third_height = 40
