Hey hive mind, I’m working on a DIY project and I’m in need of an engineering solution for a plastic closure mechanism and would love it if anyone can offer recommendations.
I need something like a small ball chain zip (see attached pic) that opens and closes using a mechanism OTHER THAN passing the cable end though a loop. The closing mechanism needs to be fast, easy, and small.
Examples might include a cable end that “snaps” into place (like a plastic snap buckle), is wrapped around hardware that holds it rigidly in place (like a Dutchwear fleaz…see here: https://dutchwaregear.com/product/fleaz/), twists around itself (like a twist cable), or hooks onto itself.
Here’s a list of more specific requirements. The zip must be:
- Ultralight weight, low profile, and small
- Flexible plastic with high fatigue strength
- Tensile strength similar to a very small zip tie (approximately 5-10 lbs breaking strength)
- Will not accidentally open up, even if tension is applied
- Quick, one-handed operation
- Doesn’t require super fiddly dexterity to operate (e.g., passing a cord through a small hole)
- Creates a loop that is adjustable in size up to 1.5” diameter
Does something like this already exist?
Or, what would be a good solution?
Thanks in advance for any ideas!
