This is custom themed EZ-Robot JD robot head, in the theme of C3PO from Star Wars. It keeps the base of the JD face/head and C3PO themed bits have been added.
The back of the head is not included and was not modified. If you require the back of the JD head you can down load it from www.ez-robot.com
I'm still new at designing 3D parts, but I used https://www.tinkercad.com and Simplify3D software to edit parts and combine them.
