I need a better (cheap) probe(holder) for measuring signals on arbitrary devices

My colleagues do this with sometimes 10-15CM wires. Signal integrity is a magic world.
I prefer soldering a small, 1-2mm hook. Best is a 1K resistor to SMA, SMA cable, BNC adapter scope, 50Ohm. 1:20.

Do you happen to work for the same company as I do?
I've seen this "technique" (the long wires) way too often.

... this would already make three of us! :-DD
seriously though, at least for the two of us, the chance we both work for the same enterprise isn't even that low...

What else would you do ? ^-^
+ on both wire hook and 1k and 450 ohm resistors terminated into 50 ohm scope...

I'm digging up an old thread rather than start a new one.
I like the Harbor Freight item (https://www.harborfreight.com/multipositional-magnetic-base-with-fine-adjustment-5645.html), but wondering if anyone has made a 3D holder?
My needs would be for various scope probes and meter leads, so I'd need something that can adapt to different lead types.
Recently I began repairing a board with 0402 components and need a spare hand. Something that would hold a probe lead and/or multi meter leads would be great.

You might want to check out Noga arms (https://www.noga.com/Products/hold/Holding%20System) (or one of the knockoffs). I haven't used mine to hold probes, but for getting dial indicators into strange positions quickly, they can't be beat.
