I designed this to mount on a cap I designed that in turn is mounted on a bearing. The opening is 24mm and fits well on a 23mm cap. Alternately, you can sink it in the bed of your slicer and just print the turntable. Since some scanners use lidar and others optics - and some a combination of those, I designed this with random profiles and patterns. I printed with a manual filament change. The first two layers in black, the rest in white. You can also print in black and carefully paint the features white. I also made a larger version.
