I have created buildings for my Railroad Town using Tinkercad. The last building I created was the town’s mercantile. If you look at the front of the building, you will notice that I created some bags of flour along with other supplies.
My thought was if the town mercantile sold flour, they would a supplier for that product. Hence, the water mill for the town was conceived. Originally, I was going to design the mechanism use to grind the grain, but it is complex. If you look in the inside you will see the beginning of the mechanism. I may complete it one day.
First I created the water wheel, which match the gears on the inside. Then I created the building. I needed a trough to direct water on to the water wheel.
The terrain had to be create and adjusted to support the trough.
The door was above water level so I needed a path to enter the building.
I copied my horses and wagon from the Tinkercad design I made for the Town Livery and loaded the wagon with copies of the flour from the town’s Mercantile design file. I just noticed the horses do not have their harness on, let me go correct that.
If you would like to see the 3D design for this building, please visit Tinkercad.
