This ladder is designed to match Duplo bricks and figures. The top of the ladder is secured on top of a brick wall/tower. If the wall is four bricks high, the bottom of the ladder will precisely reach the ground. The vertical rails are spaced to match the distance between the hands of regular Duplo figures.
The model can be printed without support. I recommend printing with PETG or ABS for strength.
The author marked this model as their own original creation.
