Remixed from https://makerworld.com/en/models/91165#profileId-97505 by TobyStoe.

I increased the scale of the original pot and then altered the internal volume to support larger plants / planters by decreasing the angle of the internal walls. I also decreased the amount of space taken up by the base to shorten the pot a little relative to its internal volume. Lastly I changed the infil within the print profile to one that uses less plastic.

This pot shoud be able to support roughly 115mm top diameter pots I think thats roughly 4.5 Inches which as far as I can tell is fairly non-standard. This variation is also signifigantly deep to the point that your internal plastic pot may not even hit the bottom however I have found this is not really an issue and in fact could be beneficial in some instances. Decreasing the plastic in the base make have made this more top heavy so in terms of stability your milage may vary.
