This is 99.9% blondofblargh's doing. I just aligned the pieces for easy dual extrusion.
Print the "softbeads" with ninjaflex or equivalent. Print the "hardbeads" with something like PLA, ABS, etc.. I would use support made from PLA, ABS or whatever hard material you're using.
SoftBand2 is the stock band, sitting directly on top of the beads. This will fuse the two materials.
SoftBand3 is slightly raised to try to prevent fusing of the two materials.
SoftBandFULL is a fatter version of the stock SoftBand. This version fills the area inside the beads, fusing the two materials.
