Self foldable spining top

This is my most advence spining top yet, it is the third one that I have published that can fold and I have used it everyday for the past two weeks becaus it is a lot of fun.With a minor twist this spining top unfolds itself and stays as such until folded back again.How to unfold itHow to fold itIt works because two half-shaft that we are gonna call arms are kept under tension by an elastic band, they can&#39;t release because of the outer ring but if you turn it, a slot will let the arms go. The spining top is printed in place so the only assembly required is the addtion of the ealstic band (ths was designed with 20mm/1.4mm elastic band which is the standart one given by makerworld in its beginner kit). Assembly: (follow the diffferent images to put the elastic the right way and you are ready to turn.) <
