Hi Moi'ers

I have an issue with cvolume script
The thing is that I have modelled a cup and I made a solid within to measure the volume.
The solid is about 240 cubic cm (according to the script and calculated as water) and that is correct compared to wanted size of est. 240 ml to the rim.
But.. When 3D Printing the model it fits 400 ml??

I have tried a bunch of translators and they all make same calculations for ccm/ml so obvisiously it must be something with my model??
