I printed these pots with a 0.8mm Nozzle and 0.4, 0.48, 0.6 & 0.64mm layer height 

Also printed one with 0.4mm nozzle 0.28mm layer height and it took 8 hours

The “Spiral Mode” one creates some tiny hole at the bottom but they are okay for a planter

Use support at the bottom for a better print

Scale it as you like :) happy fall season
