Why are some 3d models stretched?

Gamero

One of my meshes is stretched in the z axis. I created the mesh in blender. Its dimensions are 0.9x0.9x0.9 units in blender, with scaling of 1x1x1.
If have tried exporting it both as .obj and as .gltf.
In godot it appears to be about 2 units on the z axis.

Any ideas on why this happens?

often what happens is it's inheriting the scale of some parent node, or it was scaled in blender, exported, and reset in Godot.
to me it sounds like problem 1 might be yours, check the node tree for parent nodes that it might be inheriting from.
