plant pot with spherical cavities

Print with infill 0 and no top surface. You may want to adjust extrusion width - on 0.4mm nozzle I set 0.8mm width and 2 perimeters. Holes for water drain are to be drilled after print to your taste. Cavities on the bottom are for flexible feet (print with negative size compensation for a good fit) which are to be glued to the pot.
