Rugged 4x 18650 Battery Carry Case
Created 3 months ago
Description
This is a rugged and secure carry case designed specifically to hold four 18650 batteries, easily fitting into any busy tool bag or backpack. The internal slots are generously sized at roughly 19mm in diameter and 67mm long, making it fully compatible with slightly larger protected cells. A key feature is the sliding lid equipped with a robust locking latch that cannot be accidentally bumped open by other tools or gear. Finger cutouts are integrated into the design so you can quickly retrieve the batteries when you need them. You can use this sturdy case for storing extra power for flashlights, portable fans, or power tools when on the go. For remixes, consider modifying the internal slot dimensions to accommodate different battery sizes like 21700s or AA batteries, adding a rubber gasket for water resistance, or incorporating a belt clip for even easier access.

What it's for A heavy-duty mounting enclosure that now features an integrated hinge system and a reliable snap-fit latch, replacing the standard friction-fit lid.

Once printed, insert a piece of 1.75 mm filament, a stiff wire, or an M3 bolt through the hinge knuckles to secure the lid to the body. The latch requires no extra hardware—it operates via intentional plastic flex.
