C Battery Box

thingiverse

Here is a battery box designed to hold four 'C' batteries, ensuring durable and secure storage. I use this to keep spare batteries for portable radios, such as an old Broadmoor multiband radio, a Longines World Traveler multiband radio, and a newer Radio Shack AM-FM-SW-Weather radio. This setup is similar to my AAA Battery Case, but it's a 2x2 case, rather than a 4x1 case. The friction fit cap has a .05mm radius clearance, allowing it to slide and hold perfectly in place. I printed this design in PETG, but PLA would also work well, as would any other favorite filament you may choose.
