Móc Carabiner Có Lực Kẹp Sẵn

As suggested by several makers of Filarte3D's model, the closing force of the arm can be increased by moving the arm outside of the model - essentially bending the arm outward. 

This is exactly what I did - resulting in this model. After printing, the maker would just need to bend it inwards and upward/downward gently to move the arm to the closing position.

Hopefully this helps users who want a stronger closing force on this beautiful model.

[Update] I've added a new model and gcode file (sliced using PrusaSlicer for Made For Prusa PETG) for even stronger closing force. Use the CarabinerExtraPretension files if you like the arm to close tighter.
