Snow pile for wooden train tracks

Model of a snow pile which can be added on top of a wooden train tracks like Brio, Playtive, Ikea, etc. It can be used to play with train stuck in a snow blizzard. Printed in gray can be used as a stone blockage on the train track.

There are three plates:

1. bigger pile
2. smaller pile
3. four small piles

Attached pictures show printed in white PETG (I didn't have a white PLA) and gray PLA.
