How can I convert a model from *.x_t to *.obj?

Question

3D

I want to display a 3d model on the site (with the ability to pull and twist). Now it is in x_t format. I do not want to use ready-made viewers, I use three.js. To do this, you need to have a model in obj format.
Question: how to convert the model?
PS. Installing Autodesk Inventor (40 GB) is the most undesirable option.
