Rigid Bodies for Lego models

Hi there,

I’m working with rigid bodies for the first time. I’m using a model downloaded from Mecabricks which has lego models. When ever I apply rigid body to the objects they explode. I’ve read about why others have exploded but have been unable to stop it on my model. (The model is that big because of the way mecabricks operates, best not to scale down)

Does anyone know what is the problem is? Thanks in advance!
