Fastener - Force Activated Release - Breakaway Lanyard

This is a fastener that releases when a certain amount of force is applied. I'll be making a few more - working my way up to 30 lbs or 14 kg.

V1.1 Releases at approx. 8 lbs or 3.6 kg
V1.2 10 lbs, 4.5 kg
V1.3 12 lbs, 5.44 kg.

Applications. attachment to things that may be damaged when too much force is applied. As a safety feature to help prevent choking or entanglement. If you get ideas, please let me know. I am working to allow installation of various things at public schools wit
