I just received a half-kilo spool of NinjaFlex (which is rubbery, but it's not 6800 miles long).
Some current & projected projects will call for custom shock mounts and/or other springy squishy tough bits, so this seemed worth a try. Tugging on the free end of the filament suggests that it has the right sort of properties.
It's the real name-brand stuff, not the half-price Russian knockoff, which might be worth checking out, someday, if I end up doing such things in volume. Or, once I have a design nailed down, I could just have someone else fabricate a bunch.
Update: The FlashForge's extruder doesn't like this squishy, hard-to-push stuff. I've downloaded a .stl of a purported fix; now I need to print it in ABS, disassemble the extruder, install the new part (assuming it actually fits), and then have another go at the rubbery goo, and fabricating some nanoNingis therefrom (the first planned rubbery object is actually somewhat triangular, but closer to 6800 microns along each side).
I don't think I'll have time for this today (this being Monday) nor tomorrow; got two consulting projects back in active mode, plus needing to get a provisional patent application together for that de-weaponized guidance system, and I didn't accomplish much over the weekend.
I did learn, in tugging on the filament, that the material is very tough indeed. Have to see how it comes out when printed at 90% infill.
