The prompt
The generated model is incomplete. Rebuild it using the uploaded reference image as the primary geometry guide. Create a full-scale, detailed 3D BBB microfluidic fixture with five properly sized layers: top PMMA, vascular PDMS, PET membrane, brain-side PDMS and bottom PMMA. Include visible internal channels, two vertical vascular ports, two lateral brain-side ports, four corner mounting holes and four M3 screws. Align all components precisely. Generate both a fully assembled model and an exploded model with realistic spacing. Do not create tiny floating components or simplified flat plates. Use editable 3D solid geometry.
