Cord Stop - Cord Holder

thingiverse

This is a basic project that allows you to print your own springs along the way. You'll have the opportunity to learn how to create springs from scratch. There are several Cord stop designs available on Thingiverse, but I couldn't find one that utilizes a spring to keep things in place. If you search online, you'll find many options for sale, but they can be quite expensive, especially if you need multiple units.
