I prefer not to see a soap dish near the sink, so here's an integrated soap dish for our curved sink. This way the soap always drains completely directly into the sink, and doesn't sit in a pool of water.
This "remix" was designed to lift the dish a little bit to keep water from remaining underneath the dish on the top surface of the surrounding sink edge, resulting in even less cleaning.
Here's the STL and the GCode to print (PRUSA MK3), but you may need to customize the model to fit your sink. So download the .f3d file for Fusion 360.
If you print with supports (file attached) the edge curves on the dish should come out much cleaner than my print shown without supports.
It printed and fit perfectly on my sink, but if you need to get the dish to fit the curve of your sink after print, gently heat up the 30* joint from underneath with a hair dryer or stove lighter then quickly set onto your sink and gently push down to get a tight fit to your sink's geometry.
I dubbed this version codename: "Manta"
print file with supports for better curves/edges.
I printed without supports, as I'm too impatient.
Use 5mm brim to unsure strong sticking to bed plate.
Designed in Fusion 360
Used Fusion 360 T-spline form sculpting / modeling feature to create the shape, then thickened surface to be 2mm.
