There are many detergent cup holders available for download, but I couldn't find any specifically for the Great Value (Walmart) brand detergents. The large cup holder also works with some Gain, TIde and possibly other brands of detergent. F360 and step files included for two cup sizes.
UPDATE - 7/19/25 Slightly enlarged the cup area to better accept Gain and Tide detergent cups.
