My model of Robert/People planter, this one is called “Serious”.

For medium sized plants choose medium sized version, cup size 80 mm / 3.15 inch.

For larger ones increase cup size to 110 mm / 4.33 inch or any scale you wish.

This model needs some minor supports. If you have trouble with bed adhesion turn on Brim.

I like to print these planters with fuzzy skin turned on (contour, fuzzy skin distance - 0.3, fuzzy skin thickness - 0.1).

It can be printed smooth also, just be sure to check if seam is placed at Back/Rear.

When planting cactus or succulents at the bottom I add a little bit of pebbles for drainage and then potting soil.

And don't forget to water it according to your plant needs :)
