Train track maker Nov 25 2017. This is intended to be compatible with "Power Trains", "Power City Trains" or even "Power City" sets. Mating surfaces provide a close fit with existing set pieces. The underside is completely flat in this design for optimization on a desktop 3D printer. No copyright infringement intended. This file is intended to be used to generate non standard track lengths. This is quite useful when building free form layouts. You might have an incomplete set, like I did, and you need to make the track ends meet.
These files already include their own supports where needed.
