This details building the ladder. First, one side of the ladder is created. The fillet feature allows the ladder to be rounded off at the top.
One step of the ladder is created, and a rectangular pattern operation creates the remaining steps.
Extrude the steps and add a copy of the side piece, and the ladder is complete.
Using a knife, I scribed some lines into the 3D printed part to simulate wood grain. The piece was painted a wood color followed by a brown wash to enhance the texture.
And finally, the ladder is glued into place.
