The prompt
Design a single solid, watertight, 3D-printable arrow taper tool for 11/32 inch (8.73125 mm) bamboo arrow shafts. Body: rounded rectangular block 78 x 44 x 22 mm, R6 corners, shaft axis along X at Y=0, Z=13.5. Shaft channel: two conical mouths joined by a 4.80 mm relief, with 1 x 45 degree chamfers. Point end: 8.85 mm diameter at X=0, 5 degree half-angle, tapering to 4.70 mm at X=23.7. Nock end: 8.85 mm at X=78, 11 degree half-angle, tapering to 0.80 mm at X=57.3. Blades: two KUM 500S blades, 23.7 x 6.35 x 0.70 mm, central 2.70 mm hole, one per end. Blade bays: two identical recessed pockets on the +Y upper shoulder. Each seat is a plane tangent to its cone along the 50 degree generator, offset 0.40 mm inward. Pocket 24.1 x 6.9 mm, normal to the seat, floor on the seat plane, inboard edge open to the cone, blade edge protruding 0.40 mm. Point pocket X=0 to 24.1; nock pocket X=54.2 to 78. Screws: one M2.5 x 3 mm pan-head screw per blade. Pilot 2.0 mm diameter x 2.2 mm deep, normal to the seat, at X=12 and X=66.15, 3.175 mm from the cutting edge. Do not break the pilot into the cone. Print with the shaft axis vertical, no supports. Export a manifold, watertight STL at 0.02 mm. No text or decoration.
