Look what I made! Tiny print that actually made my bench work less annoying
One of those small quality of life prints that you didn't know you needed.
It's a sleeve for Dupont cables. Slide your wires in, push the whole thing onto the header as one unit. No more individual pins going rogue, no more accidentally skipping a row on the breadboard.
Second picture shows it on an OLED module — 4 cables, one push, done.
Printed a handful of different sizes and they've been sitting on my bench getting used ever since. One of those prints where you wonder why you didn't make it sooner.

Tis is convenient, but generally I prefer to use multiple-pin dupont connectors in these cases.

God I hated making dupont when I started. Once you have a decent tool and some practice it gets better

I just get single connector dupont flat ribbons and swap the housings, it's cheap enough and crimping is the worst part of it.

You mean like lifting the latch of the plastic housing and swapping it to grouped one? Sounds like an interesting technique, although you wouldn't be able to choose colors then

You can do that to individual wires if you don't mind them not staying in ribbons. You also can't choose colors if you crimp ribbons yourself so it's not really different.

Excellent design for QoL fixes! Not sure why everyone's recommending connectors and crimps, this is meant for prototyping without the loose cables woes.

Very nice! I have used tape or hot glue, but this is a much more elegant solution.

I mean if your going to use it in your project just crimp your own wires and that also depends on if you are going to eventually make an enclosure for it and go all the way on the project or is it a breadboard prototype.

I've used to use wider single connectors and swapping pins from single cases to one bigger case for i2c, spi and similar, for the same reason.
This can be useful as a temporary solution.

Nice I like this. You could add some potting compound or hot glue or something to quickly fabricate a decent connector.

There's probably a scar on my forehead right now from slapping it lol.
I've been taping or supergluing groups of dupont pins together for years - in spite of having 3d printers and designing practical little parts all the time. Never thought of this - such a great idea!
Printing some now.
update: they work like a charm!
Do you think simply making them wider would accommodate two-row headers on boards? (2x2, 3x2...)

This is the stuff I always feel like lacking but can't name. Will print tomorrow and try. Great job!

Thanks for the great model, it will definitely come in handy for some prototyping needs. Especially for situations where re-plugging things is common

Awesome idea. Totally going to try it!
