The prompt

Great, exactly what I wanted. However, I am sorry, I messed the size of the rectangle base, outer size should be 21.8x28.2mm and the wall thickness throughout the object just 1.2mm. Also the height can be smaller, just 35mm. And the circular top should be continuous valve of 25.5mm for the 10mm from the top of the object. Similarly the rectangular base should go for 3mm before starting the transition. That means the transition should take only 22mm.
