Conure nest box dimensions

[Merv]

What are the ideal nest box dimensions for cinamon conures?
I've been told diffrent things and am now unsure..
one guy told me to make the entrance hole 5cm and not bigger or they wont go in but i've read on diffrent websites / forums that 7cm - 8cm is best.
Anyone who has experience with conures who can help me out here?
Thanks!

My gccs seem to do well with cockatiel size nest boxes, however, some of my gccs had quite literally dug/pecked/scratched out the bottom of of one or two nestboxes.

I like Birds, Etc. - nest boxes , breeding boxes , and Bird Butler water bottles for parrots .
They recommend either a cockatiel box (9" cube with 3 in. opening) or a small bootbox that they call a "small conure" box with a 2.5" opening. Birds, Etc. - boot style parrot nest box and breeding boxes and Bird Butler water bottles
