I made a plugin that shows thumbnails for Minecraft Schematics

Source code

This works for both Blueprints from the Axiom Mod and Litematica schematics, as they both embed a preview image in their respective formats.

This plugin requires creating custom file associations. I couldn’t find any publically coordinated convention, so I used the mimetypes model/prs.axiom.blueprint and model/prs.litematica.litematic. The README has instructions for this.

I would recommend you to add a mimetype for the files at

There is the start of the work for some of minecraft file:

So user don’t have to install this mimetype.

For specific applications files, the convention is to use application/x-application-...
Here probably application/x-minecraft-model-axiom or something.
