An ergonomic coffee cup designed in Autodesk 123Design. I made it in Colorfabb XT, which should resist well to temperature and be chemically safe. I actually had a few coffees with it and still feel quite well at the moment :)
Since FDM printing is known for possibly generating micro pores on surfaces, I will take great care of cleaning these cups very well after each use.
The cup prints well without supports.
