I wanted a Baby Groot Bobble head so I did this remix to allow for a 7mm inner diameter spring to attach to the neck then to a pin inside the base of the head. If you enlarge or reduce the model you will require a different size spring but it can be done.
I use a raft and support for the head as there is a now a hole in the base and a pin up inside to attach a spring to
