You can only set your character's name once, at the start of the game (when you create your world), for this reason we recommend you use the animal name method. You will then receive the quality sprinkler item.
To spawn this item using an animal's name, visit Marnie's Ranch, speak to Marnie and purchase an animal (we recommend a chicken as it is cheapest).
Spawning items in Stardew Valley is not done via commands, but rather through a cheat in which you must set your character's name, or the name of an animal, to the item code of the item you wish to spawn surrounded by.
