This is Reuben if he lived after the destruction of wither storm. It was supposed to be an alternative canon ending for the Netflix version of Minecraft Story Mode. It was scrapped because the company was going bankrupt at the same time the Netflix version was developing. For more info check the tumblr post of the lead writer of the game: stirpicus.tumblr.com/post/700247111657242624/so-in-honor-of-the-netflix-edition-of-minecraft
Use the editor window above to rotate or move the model as you want, and then click the
Get the command button to get a new command.
If you want to make more changes or completely remake the model, open the full version
of the editor using the Open in BDEngine button.
To use a command in the game, you need a Command Block, as the chat field in Minecraft has a character limit.
Now you can destroy the Command Block and enjoy the installed model. Repeat the procedure several times if there are multiple model commands in the export window.
Be sure to install Axiom [modrinth] if you haven't already.
