Dish soap dispenser,Simple assembly, all parts slide out and can be easily cleaned, there is room for sponge at the bottom, pressing with the sponge on the arm will cause the soap to come out and spill on the sponge, the spring returns the arm and closes the valve, all you need is a spring of a simple pen, the device can be glued to the wall or fixed with screws, in the zipped folders (assembly, cura) are attached precise instructions including print files and printing instructions with screenshots of the data fill as I printed them, Very convenient and useful, hope you enjoy it
