Part 1 :
I kept saying nylon plastic in my previous video , i'm not using the proper filament for 3D printing , i'm actually using the filament that is used by the grass cutting machine !, it's a very tough material and i believe combined with other stuff and it requires a high temperature over 300°C ... . but it's the only thing i could find here, so i'm testing with it , and it see to work fine . however a proper ventilation is a must ! .
