Anti-slip simple sponge holder

The model is printed from PLA with the fact that there are 4 holes 1 mm deep on the bottom, I filled those holes with silicone glue from a hot melt gun, thanks to which the holder became anti-slip.The holder also has a channel for water drainage and aeration to prevent mold from forming.
