I created a paint shaker for the Elegoo Mercury Plus station for Valejo, Army Paints and others with the same dimension.
Maybe it will also go to other washing stations, but I am not sure about the spacing of the magnets. One 608 bearing and two 14x5mm magnets are required for assembly. The dimensions for the other magnets can be adjusted in the slicer, but I recommend using strong magnets.
The bearing is firmly glued together with the magnets to the Base Shaker part. On the other side, four cups are glued to the bottles.
The Support part sticks to the Base with spike part. It is used to define the gap between the washing station and the shaker.
Finally, the Base with spike and Base Shaker parts are connected with the middle pin.
