How do I turn a model into a png file for oraxen use?

[warped cedar]

I made this model for an item in oraxen but I need a png file that will look kinda like a cube. How do I do it?

Which one?

I'm not sure what you mean, can you elaborate on what you mean by "png file that will look kinda like a cube"? Do you just mean a screenshot of your model or something else?

For example:
This is a model I created. I need it to look like thay so I can use it in Oraxen.

That's a texture, not a model
