Walking Ball Bowls

thingiverse

These bowls demand custom processing. You cannot simply rely on vase mode because the bottom of the ball part is too shallow and the layers are too far apart, so they will sag or fall out. The trick lies in setting them up as you would with vase mode, but turning off vase mode, and making the walls 2 layers thick instead of 1, like they would be with vase mode. Use 2 or 3 bottom layers, and zero top layers.
