A holder designed for sponges I use specifically for build plate cleaning, to keep it separated from food cleaning and food particles. This model can also be used for any general purpose as well if you're just looking for a generic sponge holder. It holds any standard size sponge, and has a built in drainage tray in the bottom for any dripping water. Easy to print and easy to clean. The print profile has the bottom section heavier with no infill, making it nice and solid and stable on any countertop.
