Tomy tracks on Duplo bricks mounting adapter

thingiverse

This adapter enables users to attach circular blue Tomy or Thomas train tracks directly onto standard Duplo bricks. The adapter's design allows for the creation of elevated railroads that seamlessly integrate with Duplos, providing a unique and imaginative building experience. To keep the tracks securely in place, the adapter holds them firmly under their couplings. In fact, four adapters can support up to four circular segments, which can be connected to form a complete circle.
