Need help with clipping planes

Threejs examples on GitHub part of code

I was trying to replicate this line of code. I tried to replace geometry with the geometry of a loaded FBX model. Can’t figure out why it shows some really strange scale of a box.fbx object.
I iterated trough childs, the program gives no error.
Can somebody help me with this one?

Can you please share the FBX file in this thread?

test.FBX (28.9 KB)
Here it is, sorry for the late response.
