This little benchmark print helps you to figure out how well sharp corners stick to your printbed. Both the inside and outside corner are filleted with a different radii. The size of each radius can be seen on the adjacent face.
Overall, bigger radii stick better to the bed, while sharp, pointy corners tend to lift up.
After completing this test, you will know how to design corners on your own models, so they stick well and don't fail during the print.
The model is 30mm tall, so you can also test how much influence shrinkage of different materials has on the adhesion. ABS for example will shrink when cooling down, so it tends to pull the corners up.
Have fun printing and please show us your results
