Tiro il Dino – Pull-Along Dinosaur Toy

Tiro il Dino is a pull-along toy designed for young children, inspired by Montessori principles: simple shapes, clear materials, and an intuitive function.
The dinosaur features a front eyelet where a cord can be attached, allowing kids to pull it around easily.

The model consists of two printable parts:

• Dinosaur body (single-piece print)

• Wheels (printed separately and snap-fit into the hubs)

Once assembled, the wheels rotate freely without screws, pins, or extra hardware.
