I was washing dishes in the sink and hands were getting fatigued from holding the dish while cleaning. Then I tried cleaning at the bottom of the sink, but it kept sliding around. So, I had an idea of designing a device that I could insert into the sink and it would hold the plate or bowl while I was cleaning the front or back. It is pretty sturdy when assembled and also portable when dis-assembled. I made it for my dish and 2 different bowl sizes. But it can be used as a template to make custom for your dish/bowl sizes.
