Another example of Quintano man trying to help.
But failing. If you know you can't help. Don't post.
Explaining to QuintanoMaking a adding isnt just shoving the model somewhere.
Your addon requires a script, and its requires packaging.
Take a gander at the .zip files in your addons folder.
Even then, we can already see that you know how to package.
You need to check your console when trying to test the addon.
Make sure its enabled, etc.
