Remix - Battery Adapter - convert three AA to one D cell

thingiverse

To begin with, I suggest checking out Maikalguy's adapter at http://www.thingiverse.com/thing:33706. However, I noticed that his 4xAA package is larger than a single D cell and wouldn't fit in my Mag Flashlight. Therefore, I opted for this slim 3xAA adapter instead. In addition, I plan to make some modifications to it soon. Printing requires a few layers and 10% fill should suffice. Follow Maikaiguy's wiring instructions shown in his version of this remix. Use AWG24 wire for the best results. Most importantly, ensure that the cells used in this adapter are identical, with the same state of charge, manufacturer, and ideally from the same box. For rechargeable cells, they should also come from the same box and have the same number of charge/discharge cycles (i.e., be used as a set or new).
