This is a draining tray for the Scrub Daddy Sponge. The tray can be placed on the edge of a sink to allow the water to drain back into the sink while the sponge is being used, it will fit over the edge of top mounted sinks or just just placed on the edge of an under mount sink. The pictured tray is made from PETG but can be made from any filament, I would just paint or use a spray clear on it first.
