プロンプト

Model a torsion spring as ONE solid (wire and legs in one piece). Frame: coil axis parallel to Z through (X=8, Y=-6); angles about it are measured in the XY plane from +X toward +Y. Wire: round, Ø3, swept along the path below (section perpendicular to the path). Coil: helix of radius 12 (wire centre), pitch 4, LEFT-hand, 4.75 turns, from Z=0 to Z=19. It starts at Z=0 on the 0° side, at (20, -6, 0). Left-hand: the angle DEcreases as Z increases (clockwise seen from +Z), angle = -90°·Z, so at Z=1 the wire centre is on the 270° side (8, -18, 1) and at Z=19 it ends on the 90° side at (8, 6, 19). Leg 1: straight, in the plane Z=0, tangent to the coil at its start: from (20, 34, 0) to the start point (20, -6, 0), i.e. it runs along -Y into the coil. Leg 2: straight, in the plane Z=19, tangent to the coil at its end: from the end point (8, 6, 19) along +X to (48, 6, 19). At both joints the wire is continuous (fill the joint with a Ø3 sphere); leg ends are flat.
