This is a small round inkwell appropriate for holding a small amount of ink, or decoratively holding a quill on a desk.The pictured inkwell was built on a Replicator 2 using MakerWare with a 0.2 layer height, 2 shells, and 25% infill. It is pretty much water-tight as long as you have a reliable extruder (see http://www.thingiverse.com/thing:53125 to correct the Replicator 2's extruder design flaw) and at least two shells.It uses gradual angles at the base then all 45 degree angles internally and at the top, so it should build fine with no supports. The bottom center is flat so it shouldn't need rafts either.
