import cadquery as cq
# Parameters
diameter = 10.0  # Diameter of the flowerpot
height = 10.0    # Height of the flowerpot
thickness = 0.5  # Wall thickness of the flowerpot
bottom_thickness = 0.5  # Bottom thickness of the flowerpot
# Create the outer shell of the flowerpot
outer_shell = cq.Workplane("XY").circle(diameter / 2).extrude(height)
# Create the inner cavity by offsetting the outer shell inwards
inner_shell = (
    outer_shell.faces("<Z")
    .workplane()
    .circle((diameter / 2) - thickness)
    .extrude(height - bottom_thickness)
)
# Subtract the inner cavity from the outer shell to create the hollow flowerpot
flowerpot = outer_shell.cut(inner_shell)
# Export the result
cq.exporters.export(flowerpot, "/tmp/70ba5db4-27b0-4812-955c-114cf5c0fdc4.step")
