This is a custom-designed rotating base for a 3D scanner, featuring integrated visual markers for alignment and tracking. The base is nearly complete, with only one component missing to finalize the assembly: a ball bearing with an inner diameter of 15 mm, an outer diameter of 24 mm, and a height of 5 mm. The most suitable bearing for this specification is the 6802 thin-section deep groove ball bearing, which will ensure smooth and stable rotation of the turntable.
