The prompt
Model a swivel caster as seven separate solids: top plate, thrust washer, kingpin bolt, nut, fork, wheel, axle. Frame: the kingpin (swivel) axis is the Z axis; the floor is Z=0 and the wheel touches it. Top plate: X=-40..40, Y=-40..40, Z=100..105 (edges parallel to X and Y), Ø12 hole on the Z axis and four Ø9 holes at (±30, ±30), all through along Z. Thrust washer: Ø40, bore Ø12, Z=92..100, on the Z axis. Kingpin bolt: shank Ø12 from Z=78 to Z=105 on the Z axis, head Ø20 from Z=105 to Z=110. Nut: Ø20 cylinder, bore Ø12, Z=78..84. Fork, one solid, described in a fork frame whose origin is on the Z axis: its x axis is the horizontal direction (cos35°, sin35°, 0), its y axis is (-sin35°, cos35°, 0), z = world Z. Crown plate: x=-42..15, y=-23..23, Z=84..92, with a Ø12 hole on the Z axis. Two legs, 5 thick, at y=18..23 and y=-23..-18; each leg (in the x-Z plane) is the rectangle x=-42..-18, Z=37.5..84 united with a disc R12 centred on the axle point (x=-30, Z=37.5), and has a Ø10 axle hole there. So the axle sits 30 behind the kingpin toward the 215° direction, at world (X, Y) = (-24.575, -17.207), Z=37.5. Wheel: axis along the fork y axis through the axle point. Tyre Ø75 over y=-15..15, hub Ø30 over y=-18..18 (the hub faces touch the legs), bore Ø10. Axle: Ø10 along the fork y axis from y=-26 to y=26 through the legs and wheel, with Ø16 heads over y=23..26 and y=-26..-23 bearing on the outer faces of the legs.
