If u want to print this without support try to use the option “variable layer height”. It worked for me. 
To have this part fully attached to the printplate without removing the multimaterial, add a negative part (cube) to the part. Like this u can cut the model without removing the multimaterial option in Prusa Slicer. 
Dont forget to lower the cube and the TUX to the printbead to have a nice time while printing!!!

Have fun printing it :)
