18350 x4 Battery case (Rugged Box)

Simple box design for 4 18350 cells. You will need 3x M3x20 Screws. I recommend printing the box, lid and latch with “Fuzzy Skin” applied only to contours, I use 0.3mm point distance and 0.1mm thickness. EDIT: added a lower part to accomodate taller protected cells.
