Slim 18650 Magnetic Battery Case

thingiverse

This cases uses two 5mm by 3mm neodymium magnets. Magnets are embedded during the print so make sure you pause at the correct heights. The footprint of this case is very small, not much larger than the two batteries side by side, and the lid holds firmly closed with the magnets in place. The hinge is probably the weakest part of the design, though having little room to work with I couldn't think of anything better - having said that it is holding up to every day use and seems solid. Recommend 100% infill for this one. May it serve yee well! Also no supports required.
