This is a 3d printed, reusable adapter for the obsolete K battery
(KK - 4.5V, 538, 7R31, 7K31, RPX31), my own design.
It simply takes 3 of the common LR43 batteries (not included), making it easy to revive pocket instamatic and Minolta pocket cameras, or other devices that used K batteries.
An original K battery (red) is shown in the photos for comparison and is not included.
Please note that due to the nature of 3d-printing and the fact that I might be updating the design, the adapter you receive might have small imperfections and look slightly different (also in colour).
