i like to show you the custom Plaguetank 3d print i design for my wh40000 deathgurad and caos army.
This model is designed to have the same dimension of an imperial Rhino.
the model is designed in multpiple parts that need to glued, i printed them in a standard fdm 20x20x20 printer but you can do it basically with every 3d printer.
have fun.
