Had the customer asked me about the feasibility of putting a cubby grid in a non-rectangular space, I would have advised against it. But he didn’t ask. He just designed and bought, approved the drawing, and after his order arrived, had been assembled assembled, and put in the drawer, he took the following image and sent it to me. That was the first time I knew about the curved drawer front.
No, it’s not perfect, but he says it works for him and he’s happy. Notice he filled in the gap in the front with glasses cases.
So there you have it. Now we know.
