I made a quick release keychain that can be pulled apart by a little force. Use it to easily attach to belt, key ring, key chain, backpack, bags. Also can be used in sports equipment, pet products, etc.
There are 2 variants in the file ! Inspiration for both was a water buoy
The design of the left one is full plastic while the right one needs a simple O ring inside to fit snuglly, I found this one to work best, as the fit remains snug.
