The prompt
Design a rigid, resin-3D-printable, two-part master mould for casting a flexible, food-safe silicone butter mould. The finished silicone mould must contain 60 vertical cylindrical wells arranged in 6 columns and 10 rows. Cavity specifications: Internal diameter: 20 mm. Internal depth: 45 mm. Straight, parallel walls with no taper. Completely flat circular bottoms. Critical design requirements: The finished mould must consist of 60 individual flexible cylindrical wells connected by a thin silicone framework. Avoid creating a thick, solid rectangular block of silicone surrounding the cavities. The connecting silicone structure must be sufficiently thin and flexible to allow each well to flex independently of its neighbours. Each cavity must have a flexible bottom membrane that can be pressed upwards from underneath to eject individual butter cylinders. Design the rigid master using removable cylindrical cores to create the cavities. Account for silicone wall thickness, flexible connecting sections and bottom membrane thickness. The master must allow the cured silicone mould to be removed without damage. Do not introduce taper into the cylindrical cavities. Before generating the CAD model, propose suitable silicone thicknesses and explain how the design will achieve independent cavity flexibility. Ask me to approve the proposed dimensions before proceeding. Deliverables: Editable parametric CAD model, dimensioned engineering drawing, STL and STEP files.
