Look in https://www.printables.com/social/261776-brass_ring/collections/224415 for other sizes. These battery boxes are printed as separate parts that are printed in orientations chosen to maximize strength and then snapped together. The box halves require moderate infill (10%-20%) and can be printed with no supports, but I prefer to paint on supports under the flat sections on the hinge hoops, the latch brackets, and the latch catch. I printed with 0.16 layer height in PETG and PLA. Assembly instructions: 1) Snap the hinges into the box bottom's hinge hoop making sure that the hinge tabs are fully engaged and locked in place. 2) Flip the hinge tabs to the up position and place the box lid over the box bottom with the hinge hoops over the hinge tabs, press the box halves together until the hinge tabs fully snap into the hinge hoops and lock in place. 3) Push the tab of the latch through the latch hoop on the box lid until the latch tab fully locks in place.
