Villeroy & Boch

The half-round shape on the bottom of the model is made like that on purpose, as there's a spring in the sink that makes the cover cap stick firmly to it (pic 3). Top has rounded edges, I'm a bit proud how smooth and non-sharp it went ;) 
(And yes, kinda looks like the V&B original, but its ergonomic yaknow)

I know it's easier to print it top on the build plate, but I did it otherwise to prevent the ugly surface made by the support. Good thing you cannot see the bottom.

I included a print file with tree support ‘cause it’s easier to remove.
