Why using universal measuring cup, when you can print one for your requirements. I am using it for washing powder and suchlike.
measuring cups for 10 - 150ml and 1/4 - 5 fl oz (US and Imperial) already generated. Or open it in the Customizer and generate your own measuring cup.
The default wall thickness is 1mm. That is ok up to about 100ml for larger cups please use more wall thickness.

I have printed my scoops, up to 90ml in PLA, 0.2mm layer, 20% fill, no suport.
Maybe you will need brim.
I have checked my cup and these cups are quite exact, mine are only a little to small, about 3%. I don't worry about that.
