I originally struggled with an UP plus 2 printer in my first attempt…no offence to up owners but with my Zortrax M200 this time around has been an absolute delight. Everything fits perfectly first time. Thanks Gael for all the upgrades to the head! The encapsulated nuts for joining the skull sections work a treat, and the eye mechanism has allowed me to be a little more creative with my choice of eyes……..more on that soon……
