Very easy to print with no supports needed, this pot was originally created to house haworthias and other small, slow growing cacti and succulents. We have found it is in fact perfect for many other applications such as seed starting, rooting cuttings, etc. The drainage holes come up the sides of the pot allowing you to keep the pot on a flat surface while still allowing for drainage, and the facetted corners allow you to easily pick out a pot from the center of a tray when bunched in a seed starting tray. Various thicknesses were tested and the 1.5mm gives great strength while keeping material cost low. The original print size is 4x4x4.5", but I have also printed as large as my ender 3 will allow to create a much bigger pot, perfect for larger plants.
3D print with PETG, original size is 4x4x4.5" but can print at any size. 3 perimeters, no supports, 15-20% infill.
