Dashboard Dancing Bobble Hula Girl - (The overall size of the Dashboard Dancing Bobble Hula Girl is 73.2436mm length x 71.99mm width x 166.535mm high)
The spring needed to be used for her to bobble is 8mm x 8mm x roughly 38mm
There is no grass skirt that comes with the model so you're going to have to think of using something to use in replace of a 3D printed model, like for instance using actual hey or even some nylon twine or Natural Twisted Jute Rope. I'll leave that up to you to decide. Happy printing!!!
Thank you and Enjoy!!!
