The dish is curved in the die itself and once I extrude them I lift the ends slightly as well . !/2 of them have drain holes say for inside showers-the other 1/2 do not=they sell about the same-people like choices. I like the non drainers next to our sink .Heres the die photo hopefully you will make your own style-this shows where ridges and the foot is. its 3 3/8 inch wide. I had to modify my Brent extruder head cap (cut some away) to use this die Make as much of the cutaway profile details i
