Customizable case for AA, AAA, cylindrical batteries

prusaprinters

<p>3D-printable storage boxes for small sets of cylindrical batteries.</p><p>Designed to be leak-resistant: the body and lid have full-length overlap and there are no unnecessary openings. They are also a very snug fit so they should be secure without any additional fasteners.</p><p>Modify the second argument to <code>battery_case()</code> to set the number of cells the case should contain. The largest sizes that I have tested out are 6 × 1 cells and 4 × 2 cells.</p><h3>Printing</h3><ul><li>Use an extrusion width of 0.4 mm, and 2 perimeters.</li><li>Optionally, use no infill and no top layers — there's plenty of strength without them.</li><li>I used PETG plastic (3D Solutech clear) with a layer height of 0.3 mm. PLA should also be fine but I have not tested the final dimensions.</li></ul><p>You may need to adjust the clearances depending on your printer and filament characteristics.</p>
