I always thought the steam and water knobs on my Expobar Minore IV looked unfinished with the screw plainly visible so I made some covers

As the cutout hole in the knobs has straight sides , I needed to make the covers in 2 parts. The base is held in by the original screw and the cover clips into the base.

I found that they are easy enough to remove for maintenance and just look so much nicer
