The design in mind was for something that would accommodate a logo or some sort of branding on the cap, and for a supper rugged hefty feel. Printed with 30% infill and 3x walls for added strength, the gapping is perfect for an air-tight connection between the two with the provided corresponding O-Rings. Scaled to 50% it's perfect for a multivitamin or emergency aspirin.
