heres a adjustable measuring scoop that measures 1 cup, 1/2 cup, 1/4 cup and 1/8 cup. you adjust/slide the top to the desired portion then you just fill the end of the scoop with the flour/rice or whatever. take the place of 4 measuring cups. (and no fumbling around the cube if you know what i mean).
i got the idea from Adjustable Measuring Spoon by Danimal_FPV. his is different from mine but i use his files to make mine. his design is for teaspoons where mine is for cups. his design inspired me to make this version.
