Printed right from the file, you can fit a 2.5" pot into the planter if you like to double up like I do, or you'll have the entire cavity of the Oddish with a 2.5" diameter opening for your plant. Print with or without drainage holes. Tray to place underneath the Oddish can be found here, but I attached a resized file as well: https://www.printables.com/model/146435-lightweight-drip-tray-for-the-pokemon-bulbasaur-pl
The author remixed this model.
The bottom is still rough like the original model, but sanding takes care of that. No need to scale to hell and back, it's already set for a normal size planter.
