About this model

Included STL file. Its designed for Atwood Toys Impact Marble Run to sit in the side slot of the straight pieces. NOTE** This is designed to only work one way. It must be on the left side so that marbles are deflected to the side and go in through the tunnel along the side of the wall. You may also need to file down the side of the mountain opposite of the tunnel so that marbles that don't enter the tunnel can pass on the opposite side [Usually depending on your print settings].
