Info:

• well I like a lot 2 existing models and I have just combined them :)
  • @BuildX model is great for locking hook
  • @Breaks'n'Makes model is great for its simple shape
• so this carabiner has the same simple shape + locking hook

Dimensions:

• its height is 6,5 cm
• adjust scale if you want other size

Print info:

• use PETG for flexibility
• use brim for textured plate
• i used 8 perimeteres - so whole body is made from perimeters only for more strength
• 0.2mm layers

When it is printed, it may be little bit hard to separate the lock ends from each other, but little bending/twisting with hands should do the job quickly.
