Hollow Ribbed Pet Bowl Stand

Create a precise 3D-printable CAD model of a hollow ribbed stand for a removable metal pet bowl. This is a BOWL HOLDER, NOT a bowl. DIMENSIONS: • Stand height: exactly 75 mm • Maximum outer diameter: exactly 170 mm • Top inner opening diameter: exactly 160 mm • Top wall thickness: 5 mm radial • Metal bowl height: 70 mm The stand is 75 mm high and the metal bowl is 70 mm high, so the bowl must remain approximately 5 mm above the floor when fully inserted. INNER CAVITY — CRITICAL: The inner cavity MUST be conical/tapered. • Top inner diameter = 160 mm • The inner diameter must progressively DECREASE toward the bottom. • The inner wall must slope inward continuously from top to bottom. • Do NOT create a vertical cylindrical Ø160 mm hole. • Do NOT keep the same diameter throughout the height. • The bottom of the inner cavity must be noticeably narrower than the top. The metal bowl is inserted from the TOP and rests against the tapered inner wall. EXTERIOR: Create a clean cylindrical stand with multiple evenly spaced horizontal circumferential ribs. The ribs must run continuously around the entire circumference and be symmetrical. CONSTRUCTION: • Completely hollow • Open top • Open bottom • NO bottom • NO base • NO legs • NO feet • NO logo • NO text • NO handles The exterior must remain ribbed and symmetrical. The model must be: • rotationally symmetrical around the Z axis • dimensionally accurate • watertight • manifold • suitable for FDM 3D printing • measured in millimeters Export as STL. FINAL CHECK: Outer diameter = 170 mm Height = 75 mm Top inner diameter = 160 mm Inner cavity gets progressively narrower toward the bottom Open bottom Open top No legs No bottom No logo No text Ribbed exterior Do NOT create a solid bowl. Create only the hollow ribbed stand that holds a separate metal bowl.
