Filled to the brim, this cup should accommodate ~224 ml, which is approx. 1 Cup. Interestingly a scoop of compressible ingredients such as flour can be up to 1.5× the weight of the same volume sifted. 
Version 1 was made with Blender while version 2 was made with OpenSCAD and has the following advantages: 
+ Parametric - 1 Cup, ¼ Cup or any other measure such as ¾ Cup can be generated by changing the parameters if you have OpenSCAD 
+ Braced - The joint between the handle and the scoop should be stronger 
+ Higher definition - The circles and ellipses should look less polygonal 
The 1 Cup STL is from Blender while the ¼ Cup measure is exported from OpenSCAD. 
The walls of the cup are 3 mm wide and the handle 5 mm deep.
