This is my version of the AA to C battery adapter.

I tested it with all the different types of batteries I had at home and it was perfect for most of them but for a couple of rechargeable ones it was a bit tight but still ok.

I designed it with a wall thickness twice that of the 0.4mm nozzle width, which makes it strong enough while still being a bit flexible. I made the edge a little wider at the bottom, partly to get a larger area for the first layer of print and partly to get some stability of the adapter.

Printing and print settings

Print the battery adapter upright on its bottom, as oriented in the file. Use for example PLA with a layer height of 0.2 - 0.3mm and a nozzle width of 0.4mm.

Feedback is always good. To encourage me or other designers to make more models, please hit like and/or post your makes. If something doesn't work or is missing and can be improved, please leave a comment.
