I designed this cord lock due to rushing to get ready for camping and the manufactured cord lock broke which is years old so I needed something to work in a short amount of time.

It does require a spring which the dimensions are in the picture for the spring (this was already in the one that broke so reused that one)

Here is the broken one and 3d printed one. It also twist locks into place and doesnt require support for printing.

This is the fixed 3d printed one

Any questions please ask.
