I've been thinking of doing something similar... cause some lith developer/paper combos I've been using take 15mins to develop, which is a long time to rock a tray!
I think if you put the device on some kind of foam/rubber mat, the noise is a whole lot less loud. It seems to be amplified by the worktop it's one. In the construction itself, it might be possible to mount the motor to the frame with some kind of bearing/coupling that doesn't transfer the vibrations as well as directly bolting it onto the frame.

If I find it annoying enough I will add an isolator to the stepper. The base already has a soft rubber layer. The mic on the phone makes it sound much louder than it is. The remaining issue is the driver is, at best, half stepping
Well done!
Now you can perfect it by increasing randomness of the agitation by getting it to alternate - lift and return one near corner, then lift and return the other near corner .
It is absolutely hypnotic to watch that video!

I think you could print the lifting-rod structure, which is now two symmetric arms that are aligned with the rotation axis, as a slightly more complex structure with the arms offset from the rotation axis in different directions. This is a little hard to describe in words, but imagine that the rotation axis of the lifting rod thing is the center of a clock. Try placing the base of the arms offset to the edge of the clock, say one base at 1 o'clock and one base at 5 o'clock (or 7 o'clock if you need symmetry), but the arms both stick out in the same direction, to the right. As it rotates, I think the high end would transfer from one arm to the other, allowing the tray to rock side to side.
