My Customized Gravitrax compatible basic tile with six exits

Now I'm on the next level on learning Fusion 360. It's getting better from day to day. I also added a F3D file which is partially included.

Changes

4730808 has 2 edges that are not filleted, which makes the basic tile very odd when it comes to rounded edges. I also made the teeth solid so that it's easier to print, made a 0.5mm fillet on the inner edges on such basic tile and made 0.25mm offset faces on the rail holes for a tighter rail grip.
