Is there a minimum width to the vertical posts of a צורת הפתח?

Question:
The Gemara is very exacting with the mathematical calculation of the ratio of the circumference of a circle to the diameter (3:1) taking into consideration the thickness of the walls of the basin.

Questions on the Gemara earlier on the Amud
The Gemara brought a scenerio where a mat is placed over a קורה and the mat is suspended in the air 3 tefachim or more from the ground. The קורה is disqualified because it is not visible and the mat does not serve as a mechitza since there is a gap of three tefachim between it and the ground.
