I created this because we like to buy around laundry detergent and fabric softener from Costco. We set these on top of our top-stack washer and dryer. After every use, a little bit of detergent would leak down the machines, so I created the detergent buddy to hold the dispenser cup. Now you can fill up the cup with what you need, and place it back in the cup holder to catch anything that might drip down.

To install, you need to place the ring around the nozzle area and push down firmly. It will be a tight fit but will eventually snap on. When you need to swap out the detergent, simply pull from the bottom and the prongs will slip around the nozzle.
