Mexican Train 12 Domino Hub - Flat, Simple, Great

My friend group plays Mexican Train with a double 15 set of dominos sometimes, which can handle groups of 12 easily, but the center hub from the box only has 8 slots. This one has 12. All of the other 12-hubs I could find on Makerworld were unnecessarily complicated, thick, or would obstruct players' views of dominos on the other side, so I made mine thin like the original 8-hub from the box, but with a thin railroad detail for fun. I used Black PLA Basic for the base and Silver PLA Basic for the rails.
