Simple soap dish to replace a shattered one, came out pretty nice and being used for a almost week already.

Use 0.15 mm or lower for a smoother contact surface with the soap. I used multiple processes in Simplify3D so I went with 0.3 mm up to the contact surface, then reduced to 0.15 mm. I think 0.1 mm would be perfect for this area.

I recommend 3 perimeters and at least 3 top/bottom layers.

I only used supports on the bottom but the surface printed on top of it didn't come out quite nice. You can try bridging this area and see how it goes, it's on the inside anyways.
