The bowl was designed in two parts:
A wooden "aesthetic" part that is seen when the iris is open
A plastic cam track sleeve that rests on the bearings of the cage and dictates the vertical motion of the bowl
Plastic Sleeve
Plastic Sleeve
3d printed cam track to guide the bowl up as the cage rotates around it
The flat horizontal portion of the track keeps the bowl at a constant height below the petal end points for the first 45 degrees of the table top's turn
The curved angled section causes the bowl the rise 0.57 in in the last 27 degrees of the table top's turn
The notch at the end has the same radius as the bearing and acts as a hard stop to prevent the bowl from slipping into the next track if the table top is over turned

Wood turned bowl insert allows the bowl to maintain aesthetic continuity with the rest of the box while allowing the complicated geometry that interacts with the bearings to be 3d printed
Two 5/16' shafts were press fit into the wood act as guide rails to keep the bowl aligned on its way up and down

Shaft Alignment tool
We designed an alignment tool that sits in grooves in the plastic sleeve to ensure the placement of the guide rails in the wood was perfectly aligned with the location of the guide posts in the bottom plate.

Guide Posts
Two 3d printed posts with holes slightly larger than the diameter of the shafts in the bowl were press fit into the track to keep the bowl from spinning with the cage and maintain the linearity of the vertical motion of the bowl. Additionally, these posts act as hard stops for the angular motion of the cage limiting the turn to 72°.
