Print it in Ninjaflex at 70mm/s with the Flexion Extruder
This is a flexible variation of the same octopus that has been modified by many others. It was printed on a Makerbot Replicator with this new flexible TPE filament:
Makerbot Replicator (original version with the MK8 spring loaded extruder upgrade).
Extruder temp: 215 C
Platform: Room temp, bare aluminum, glass, or Kapton tape all worked well
Standard Replicator settings worked well, but I got the best results after I played with the retraction settings.
Retraction Settings (In Skeinforge under Dimension tab):
Minimum Travel for Retraction: 1.0mm
Retraction Distance: 2.0mm
