Description

PDF

Use this part in a necklace to prevent accidental strangling. It snaps under extensive tension e.g. when the necklace is accidently pulled into a machine or gets hooked up somewhere. Especially useful for kids' necklaces holding a key.

To be used with 1 … 3 mm lace. Rescale model for other sizes. Make sure it is printed vertically (as in the project file).

I used PLA 0.3 mm layer height. No supports needed. 

Off course, material choice and slicing have a huge impact on breaking tension.
