Technical
Printing with support (8-12%) would be ideal.
PLA would be an easy choice (no build plate adhesion would be needed).
CPE would give an nicer touch (glue stick is to be used for better adhesion).
After the print, please carefully remove the built-in support in between head and chest with cutter knife, so that the Play/Pause button can be pressed.
