Your height adjustment lever should look like this. Herman Miller should be able to provide a replacement...but consider making your own (since this feature is still working. Perhaps a golf ball (painted red) with a hole drilled into...and glue.
Thanks for the close-up reference pictures Mark, do you know if the handly-bit is detachable from the "stem" and if so can you confirm that mine is broken?
But yeah, I've got a few ideas of things I could do to jerry-rig it.
yes, the "handly bit" seems to be detachable..as I can feel an attachment point ( very small hex screw??) underneath the lever. But I'm usually wrong. And more.
