In the interests of reducing overall vibration, I stuck bearings on the top of the threaded screw. I knew when I did it the difference would be unnoticable in terms of print quality, but it did reduce noise a little. The threaded screw moves completely freely (since it's 'held' inside a bearing) but can no longer vibrate against the inner sides of the acrylic.
