I printed this ramp https://www.printables.com/model/212956-hot-wheels-ramp-and-sta for HotWheels models of my daughter and decided to make some track segments to have more control over the car's trajectories. Also, I made my variation of connectors to make a connection between either segments or the ramp and segments sturdier. For your convenience Fusion 360 file is included as well.
The author marked this model as their own original creation.
