There are plenty 18650 charger cases to be found online, but none fit my battery terminals quite right. \u003cbr\u003eThus I decided to make a 18650 charger case model that's fully \u003cstrong\u003eparameterized for readymade battery terminals\/contacts\u003c\/strong\u003e. The parameters can be changed in Autodesk Fusion.
