9 Dummy AA batteries

How: Completely redesigned with Blender. Starting with a profile, I used the screw modifier to transform it into a hexagonal "cylinder" with a bulge for the positive terminal. I added eleven smaller cylinders and used them to cut out the holes and dents. Another shape was added to cut out the opening. Exported this as *.stl. Imported it in Bambu Studio. Copied the object to get 9 AAs closely placed together. Exported it as one object in *.stl file. Imported that in Blender moved the batteries closer to each other. Added a fence around them. This to avoid tumbling over during print. Exported it as *.stl file. For printing used no support and outside brim only.Features: The bulge for the positive terminal is slightly smaller than the original. The to be placed wiring is better reachable as the gap is wider. A hole was added on the "back" side. The wire can pass through there, with a knot on the inside for tension relief.
