This is a flexible pad with nubs that scrub away gunk on dishes and the sink surface. It doesn't hold soap really well, but it is great for scrubbing dried residue. The flexible design contours to most dish surfaces. Since it is made from impermeable plastic it is easy to wash off after use. Set with the flat side up to drain away water after using.The scrubber pictured here was printed with PLA at 0.1mm layer height with an 0.8mm shell thickness.
