	This design requires "underhang" (underside support) as there are some areas which are "in air". The main box is best 3D printed "flat" (not upright). A 0.4mm nozzle (or less if desired) is recommended. 100% infill is not a hard requirement. Standard PLA is not entirely recommended given that the cells will get warm under load and charge: if they approach 60C (the glass point of PLA) the packs may begin to warp, which would be bad.
