This model is inspired by a character in one of my favorite science fiction robot movies "Robot Jox", and the Alexander robot.
The model comes printed with connected sprues (WOOD BASE AND METAL CUBE NOT INCLUDED). You will need to cut these and then sand, dremel, or file down the excess. Once you position the parts in the orientation desired, I used "Gorilla Super Glue" to make it permanent.
The "wrist" is designed with a 1/2" dia hole to allow mounting to a dowel, or whatever you'd like. You can also simply glue it down as-is.
For a video showing how I created the part, as well as how I created the piece pictured, have a look below.
Thanks!
