This is a small filament spool clip.
This is a second version.
More flexible, stronger and tougher than the 1st version.
- The shape was changed in order to solve the problem that the grip is slightly weak against a thin spooler.
- The slit shape has been changed in order to increase the resistance to destruction when it is widely spread.
- Since the slit of the 2nd version is narrow, I want you to devise modeling so that the slit does not fill up.
