I created this model, and iterated it based on my specific sink. It has a large lip, and thus needs to be rather tall.
I'd recommend increasing wall count to 4, and printing in PETG to last a little bit longer, but I've printed it in both PETG and PLA.
If you position the model to print on its rear you won't need supports :)
I designed it in Onshape with the Grid Extrude FS (Ovyl) plugin for the grate
