Problem: I'm tired of trying to balance soggy sponges and other sink implements on the sink. They inevitably fall into the sink and get wet, dirty, or lost under dishes.

Solution: maybe I can 3d print a little caddy for all our sponges that helps it all balance on the center divider, where we tend to put stuff. It should be unobtrusive, and if it could have some mechanism to stay at the back of the sink, that would be great.

Calipers: the divider, in addition to curved edges, flares slightly towards the middle and towards the bottom of the sink. It's narrowest at the edge, ~40mm, flaring out to ~41mm 6cm in towards the center. 4cm down, those numbers are ~42 and ~47. That should be good enough for Sinky to prefer the end!

I wonder if we can also capture part of the curved corner...?

It needs to drain, that's important!

Let's see how that works. It definitely indexes against the edge and basically fits. I didn't model the vertical flare, so there's a bit of a gap, but it doesn't seem to be a problem. I'm realizing the cutouts in the top saddle section are probably a bad idea - they are just cups to collect water. Maybe add some better drainage there.

Filling it up, it holds everything in place surprisingly well, especially considering how many compromises I made in the design to accommodate my level of CAD skills. This definitely proves out the concept. I hope to iterate further to make it even better.

On to the next one!

The gaps at the top could be fixed by modeling in the vertical flare of the divider and the radius of the curve of the sink corner should also be bumped up a bit to make the fit better at the end. Overall, tho, I'm pretty darn pleased with this as a quick 3D print that solves a real problem in our house.
