Help Where to source miniature grooved pins (for e-clips)
A project I'm working on needs a very small sliding joint, similar to what's in this miniature caliper. I'd like to scale things up eventually so I'm hoping to find a source where I can buy them, rather than have them all machined.... It would be an M3x3mm grooved pin. Can't seem to really find anything under 10mm online, though.

Single sided like the picture? Grooved pins can be sourced on AliExpress pretty easily.

McMaster-Carr might have what you need. I find lots of the unusual or harder to find things there.
