Hive-style storage wall (HSW)Multimeter test lead holder. I use it to store my Fluke TL75 test leads/probes, but it should be suitable for most brands. The gap between the two rods is 11 mm.

To install this model, you need an HSW connector, for example.https://makerworld.com/en/models/133125And this model can slide into it.

There's no need for support, and you can use basic PLA to print it. It can't withstand a lot of weight, but it's enough to hold a few cables.
