It mentions DuPont wire connectors which is colloquial for a common form of jump wires: the ones that can connect to breadboards, or male or female pin headers. Basically a so called “DuPont wire” is an electric wire with a pin header (either male or female) on each end leading to 3 kinds (not counting ones having multiple connectors on each wire) as male – female is the same as male – female:
- female – female
- female – male
- male – male
Being able to group the connector end of multiple jump wires in one enclosing connector for quick opening and closing is a great idea.
Hopefully the 3D printing files will be released somewhere.
One of the comments is also inspiration for a future 3D printing project:
Something I’ve been playing with is making Molex KK clone connectors. With a little bit of looking at their drawings, you can easily make housings to turn DuPont-style wire and board connectors into Molex KK-compatible ones (as well as “illegal” male wire connectors and female board connectors). I’ve been running I2C off of perfboard with the adapters and it works like a dream.
There’s also the added bonus of being able to interface with things in the KK ecosystem like PC fans. That means you can make your own PC fan extenders (or shorten too-long cables) using crimp connectors and headers you probably already own, which is extra handy.
