About this 3D model

Created a small Battery Holder for 18650 batteries. Used the tabs from a Livy Protect - Smart Ring or from here: https://s.click.aliexpress.com/e/_9GCGCT and https://s.click.aliexpress.com/e/_9JBPZ1 You will need both styles. The spring part for the mass (negative) and the non spring part with a circle in the middle for the positive.
