Just a simple scoop having a volume of 65ml, as that is what my detergent calls for. The width fits my dishwasher perfectly, to make dumping it in the compartment easier, your milage may vary.
Prints really well with the supports I used in my .3mf file. The cup has solid walls and the handle a bit more infill, as it is thin and can use some extra strength. Still only uses 13 grams of filament overall.
