For the Topo PLA wood, the four double-ball joints connecting the body to the arms and thighs have been scaled down to 92%, while the single-ball joints on the forearms and palms have been scaled down to 95%, making assembly effortless!

It’s recommended to print all joints with solid infill. For assembly order, first attach the ball joints to the body, then mount the arms onto these ball joints. Similarly, for the limbs, insert the small ball pins into the limb parts first—this way you can hold the limb steady while attaching the ball‑jointed section. If it doesn’t fit properly, try scaling down slightly, reducing by 0.98 each time; avoid drastic adjustments.
