A great way to test new filaments and have on hand an example of how they print. Both standard and mini sizes have windows of varying thickness with 1, 2, 3, 4, 5, and 6 layers at 0.2 mm layer height. The final partial windows is a small overhang test to see overhang quality. Four circles are 1 mm, 2 mm, 3 mm, and 4 mm and allow for swatches to be held on a chain or cord.
The author marked this model as their own original creation.
