change model texture [1.14.4]

[Lunatic_Cat]

Hi, I created a cassette player, after many hours spend on it everything work properly but I still have one thing I would like to add, but sadly I have no idea how I could do that.
I have 4 models for it : "open" "closed" "open with a cassette" and "close with a cassette"
currently the cassette showing in the block is a default cassette texture, but I would like to change the texture based on the cassette the player put in, does anyone have a idea how I could do such a thing?
here is how the cassette player look right now

You could use blockstates maybe

You can do it with tileentity renderer.

TileEntityRendererby Mjcty or

Modifying IBakedModel by TGG

 

I feel like the second one is more suitable for you since you are only moving the cubes and changing their colour.
