The file 'Hot Wheels Track Y-splitter Track 3D Printer Model' is (stl) file type, size is 77.2KB.
Remixed this track splitter to use built-in track connectors and eliminate 95% of the support required in the original. Support is only needed under the connector tab edges. I also flattened the top knife edges on the track walls.
