Inspired by Rock'Em Sock'Em Robots. This model is a work in progress.
Based on the bobble head components from 3D Printy. 2 spring options and a base have been included in the files for easy access. I suggest using the stiff spring as this guy is a bit beefy. A solid .step file and a .obj with the appropriate spring hole have been added along with the STL that is ready to print.
Supports and orientation change will be needed to fit your printers ability. Possible printing optimised file to come in the future
