A simple present bobblehead printed at .3mm layer height and no supports. Simply push the spring into the box then the lid. If you can't get the lid on because the spring keeps pushing down, gently insert a scraper (like the one that comes with your printer) in between a coil to keep it from shrinking then put the lid on. Happy printing!
The author remixed this model.
Used printablok for connector and spring from ghost for spring.
