A simple model with 8 varying wedge angles of equal 7.2 mm height and 12 mm width per wedge. Intended for checking the severity of "stair stepping" due to finite layer height of layer lines at increasingly shallow angles, and to see the blending of alternating layers of color.

When viewed from the front edge, wedge angles are 75, 60, 45, 30, 22.5, 15, 10, and 5 degrees from the horizontal, left to right. 

As noted above, this was actually sketched to inspect "HueForge"-like color blending when alternating between filaments, layer by layer, and approaching shallow angles. As when using the "FullSpectrum" fork of Snapmaker Orca by ratdoux (github). Intended for compact/quick benchmark printing with enough height to visualize a few colors when painted by z.

For a better all-in-one color blending test for FullSpectrum, check out the FullSpectrum Speed Palettes.
