These models help visualize geological surfaces (beds) when their patterns are observed in an outcrop.
A dipping surface that crops out in a valley or on a ridge will give rise to a V-shaped outcrop. The way the outcrop patterns vee depends on the dip of the geological surface relative to the topography. In the case of valleys, patterns vee upstream or downstream.

You can edit this model on Tinkercad.
Use your slicer to rotate this model to achieve the different bed patterns. I used zero degrees, 45 degrees, negative 45 degrees, 90 degrees, and 22.5 degrees. Use supports where needed. The two screenshots from Simplify3D show where I added supports. The seven-thick skirt helps with bed adhesion. Use the slicer to add two pauses to swap filament. The first pause is used to create the contrasting geological surfaces, the second pause is used to swap back to the original color.
