This fixture is designed for 18650 batteries arranged in a 4-cell square (2x2) configuration, accommodating slight diameter variations. The internal diameter is set to 18.7 mm to account for battery tolerances and typical FDM printing deviations. Made from PETG, this model requires no supports during printing. The inner structure is minimized for easy removal of spot-welded nickel strips without compromising the template.
