Altoid tins 21700 battery holder
by SteffenLL
Remix of the 21700 since the lid would not close with batteries. https://www.thingiverse.com/thing:3499872 The open part in the buttom can be printed as is or you can fill it like in picture 2 with a brim. The lid will get at slight bend because of the tight dimensions. PS. Remember to keep your battery sleves pristine, especially when using a metal housing! It will blow your face of if you are not carefull
