Print profiles available in 0.4 and 0.6 nozzles.
Having the edges of the planters next to each other allows you to pour dirt on the top then run your hand over to spread the dirt into all the planters - it's very quick to fill the planters with dirt without getting dirt stuck between the planters.

The small 3x3 size fits well in a window sill.
