Customizable Battery Case (magnetic)

thingiverse

Design a custom case for cylindrical batteries with an optional closure system using small magnets. The case is tailored to fit various battery sizes such as AA, AAA, CR123A, and CR2, while the 3x3mm cylinder magnets* ensure a secure lid closure. For a magnet-free version, try this link: http://www.thingiverse.com/thing:57281. The case is printed using an Afinia H-Series printer with Octave ABS Gold and Octave ABS Fluorescent Red filaments. Note that the affiliate link is provided for your convenience. To assemble, create top and bottom pieces sized according to the battery height (dividable as desired), and insert press-fit or glued magnets into columns between batteries. Ensure proper magnet orientation, or use a magnet on one side and a steel bearing/pin on the other. The minimum compatible size is 2x2 batteries; larger sizes like 1x4 can be accommodated but lack a central magnet slot. Battery height reference includes AA (50.5mm), AAA (44.5mm), CR123A (34.5mm), and CR2 (27mm).
