BRIO Train to Street 2 to 1 and Y Intersection

To reduce printtime and material, i holowed out the "backside" of the Y intersection added the brio_two_to_one_reduced.stl

My children got a wooden train set and a wooden street set and started to interconnect the streets with the tracks ending in only one lane used or not fitting…. They complained so I designed a 2 to 1 intersection and a Y intersection so that the trains can now run on streets and the cars on tracks…
