The prompt
CAD assembly, simplified Laowa 1-5X parfocal macro lens, export STEP, separate solid parts, do not merge bodies. Optical axis = Z axis. Ignore tiny fasteners, seals, fine details. Components: 1. Main barrel: hollow cylinder, inner shoulder to mount aperture, one axial long slot on wall. 2. Front group: cylinder holder + 3 simple disk lenses, fixed at front of main barrel. 3. Zoom variator assembly: cylinder holder + 2 disk lenses + sliding sleeve + 1 radial drive pin. Can only translate along Z, cannot rotate. 4. Outer cam barrel: hollow rotating cylinder outside main barrel. Inner wall has continuous cam groove. Cam groove engages drive pin. Rotate cam barrel to push zoom assembly slide along Z. 5. Fixed aperture assembly: mounted on the inner shoulder of main barrel, no axial movement. Contains base ring, 11 thin flat aperture blades, rotating dial. Rotate dial to open/close blades. Zoom and aperture are fully independent. 6. Rear relay group: holder + 2 disk lenses, fixed on barrel rear. 7. Camera mount flange: fixed at the end. Half longitudinal section. Simple solid geometry, no fillets. Keep cam groove and aperture blade linkage.
