Made for a 10" potted plant. The stand is keyed to ensure that the halves fit together in the correct orientation. The pot will only fit flush in one orientation, so just rotate it until it slots in without any pressure.
Update 11/21/17: Created a small 1.6mm thick plate to fit between the planter and original plant pot, because the planter with 0.4mm thick walls from vase mode delaminated around some of the edges with the base and no longer holds water.
Pot printed in Vase Mode with 0.28 layer height and 4 bottom solid layers
Stands printed with 1.2mm brim, 3 perimeters, 4 top and bottom solid layers, and 10% infill
