Heya,

i am almost doe with my rack all that is left is the tubs, and there is also where the question kicks in.

How many airholes/ventalation holes should i make? between the tub and the shelf is a 1 or 2 mm space that is 0.08 or 5/64 inch. not sure of those meesurments make any sence to you guys haha i dont know if there is an metric unit in america smaler then inch.

is making 4 holes in the front and 3 holes in the back enough? thodr holes would be about 6 mm 15/64 inch.

or should i make like 2 holes on the left and the right side of the tub too?
