Bed Adhesion Border Test
thingiverse
This tests how well the filament is adhering to the print bed. If all four corners are flat on the bed, then you have good adhesion. If not, then you probably need to increase your bed temperature. You may also have to adjust your extruder temperature. Another possible problem is that your print bed isn't level.
