Dinosaur skeleton 3D puzzles: T. rex and Triceratops

How it goes together

The pieces join half-and-half: the spine and legs have slots from below, the ribs and girdles from above, at the same height. The slots are 0.15 mm wider than the plate, so a piece slides in snugly and stays put. Dots engraved on the pieces mark the order: ribs from the head back, girdles and legs in pairs.

We checked in the model that the assembled pieces never overlap and that the centre of mass sits over the feet with a margin — the dinosaur doesn’t fall over.

Who to give them to

• Kids aged 6–10 who love dinosaurs: building it yourself is half the fun.
• For a science lesson or a club — two different skeletons side by side.
• For a shelf — as decor in a child’s room.

Colour and safety

We print in PLA of any colour: bone white, terracotta or something bright. The puzzles are not certified as children’s toys: not for children under 3, as small teeth can break off.
