This is a the shadow monster (also known as the "Mind Flayer") from the Netflix series Stranger Things. He is challenging and will test the bed adhesion limits of your printer! No rafts or supports are needed but might be useful if you are struggling. I recommend black PLA filament :)
This is a challenging print. It must be printed upside down to print correctly. If you are having trouble (especially getting the head to stay in place) try rafts or rotate your model in slicer to have the head under the print fan. If you are struggling with the torso maybe consider using support. This model can be printed without either, and is designed to be challenging, so don't feel bad if it doesn't work on your first try!
