Add tower locations to build plate preview?

[Mysta]

Is there a way for delta's to show tower locations in build plate preview? Or better yet to customize? I know with preloaded machines they usually show the 'build plate' but how about for custom?

You can add a custom STL file for the machine that will be displayed in the 3D view. There's lots of threads on the forum already about how to do it.
