I saw these on Stewmac when I was lookin around. I think they are a genius design, no more sharpie marks to keep/remember your settings... But I dunno if I'm willing to give up $40 to $70 for a set of knobs!? The price quickly brought my happiness to a screeching halt

I've tested them, they work perfectly..you pull them up to adjust and pull down to lock...
But the price tag is a big  no no....my designs ussually have plenty of knbs..

just idea, with 3D printer or handmade with resin, you can build that

They look like precision machined anodized aluminum alloy with a spring mechanism... Go for it and send me a couple to test

It's a good idea, but a bit hard to justify the expense when a marker pen will suffice.
However, some of our lab equipment uses plastic knobs that work this way, so there must be another supplier somewhere.

They have some locking knobs but I didn't see prices.
