The prompt
Parametric CAD assembly, units mm. Manual foil-opening tool, axis along X, nose at +X, handle at -X. 1. Nose: solid ogive/bullet, base Ø40, length 50, fully rounded tip R10, no sharp edges. 2. Hub: cylinder Ø40 x 30 behind the nose, with 4 radial slots (6 wide) at 90° spacing. Each slot has a Ø5 pivot pin at radius 15 from the axis. 3. Fingers (4x): flat metal bars 15 wide x 5 thick, 85 long from pivot to tip. They point backward (toward the handle) like barbs. Folded = parallel to shaft; opening = tip swings radially outward. Each tip has a rounded pad R6 with a 3 mm hook lip facing the nose. A heel on each finger hits the hub at 90° (hard stop). A torsion spring on each pivot pushes the finger open. 4. Shaft: tube Ø25 x 2 wall, 700 long, fixed into the hub. 5. Sliding sleeve: tube OD 62 / ID 56, length 620, slides on the shaft. Forward position covers the folded fingers (closed for insertion); pulled back 110 mm it releases the fingers. Chamfered front edge. Ball detents lock both positions. 6. Handle: fixed grip Ø36 x 120 at the shaft end with Ø50 end knob; Ø70 x 60 grip collar on the sleeve rear end. Reference body (transparent): hollow core ID 153.5, OD 175, length 660. Inside it the fingers touch the wall at ~45°; outside they open to 90° (tip span ~212). All edges filleted ≥1 mm.
