N scale depressed center flat

This is my version of a car to hold the IoTTStick with purplehat sensor board in N scale. This car lowers the center of gravity approximately 3.5 mm below the truck bolsters compared to the version I downloaded. Designed to fit Microtrains Bettendorf trucks with medium extension couplers 003 02 022 (1003). You will need to drill out the hole to use their press fit pins. I used a .073" drill.
I printed my car upside down with supports to give the best surface for the truck bolsters to ride on.
