Oscilloscope probe Ground Spring

[prasimix]

Any idea where to find such spring on ebay that has reasonable price. I mean 10 pcs for a dollar/euro not just for one piece .

I make these myself by winding stiff wire round the smooth edge of a drill that's has a slightly smaller diameter than the probe.

Or you could 3D print something like an adaptor for an HP 1.5GHz probe, https://entertaininghacks.wordpress.com/2015/04/23/scope-probe-accessory-improves-signal-fidelity/

I found a spring inside a ball point pen that was the perfect diameter to fit my 1 GHz low-Z probes. It works!

Same.  Keep a spool of wire around just for this purpose.  I wrap it around the probe 1st then take it off and give it a twist.
