This little octopus waves his 8 little arms and flashes his 8 miniature eyes. His structure and body were made using 3d printed parts, a small motor, some LEDs, and a Smartibot robot controller to allow him to be remotely controlled.

3d printed parts: See 3d models below. I printed the body, base, and head on an FDM printer, and the legs on a SLA printer. This gave them a rounder shape without extra effort.
Hardware / other bits:
Assembly: Print all of the parts, paint them, then screw everything together :-). Some tips are that the arms needed a lot of sanding and filing to get them to fit well in the base.
The author marked this model as their own original creation.
