Cricket Golems dimensions

Hello everyone, i just wandered what are the dimensions of the Cricket Golem,
it looks like its 1x1x1 but he can’t go through a 1x1 hole entrance.
So do you have any ideas on its dimensions ?

They are probably considered 3 tall (like most units) in the pathfinder, that is why even though they could fit through the hole, they will not even try
