This is a remix of madlex 18650 battery case Model C from Thingiverse.
The case is designed for flat top 18650 batterys! If you have button top or any other 18650, simply scale the model in bambu studio to your desired measurement!
I remixed it, because i did not like the hinge. I made it print in place without the need of any bolts. Also i added the flush text “18650” at the lid and i made a little adaption on the opening lid.
