The white, small part helps me to print flexible filament with my 5th generation MakerBot Replicator. I am still working on printing with NinjaFlex. I hope that I will invent in a few days. Now I can print with a less flexible filament. The flexible part in the video is the flexible version of the white part. This part fits into MakerBot Smart Extruder 11.0

 

Don’t forget that I’m 14 years old and the youngest person in Turkey who passed CSWA exam:) I printed this with Proto-Pasta’s high temp PLA.
