Gary Seven is the major character in the last episode of the second season of the original Star .... Gary Seven's servo device is curiously similar in both design and function to the sonic screwdriver used by some incarnations of the Doctor in doctor who.

the shaft does function smoothly with minimum sanding. i printed it on 0.175 layer height, speed 40mm/s, temp 245. for the small antennae i would recommend using a pearlised pin or something similar (heat it up and push in) as you can see i have put some channels in to help with this.
