4LR44 / 4SR44 / PX28 / A544 / 28L Battery Storage Case

A compact storage case with a sliding (and click in place) lid for two 4LR44 batteries or other batteries of the same form factor. Designed for batteries approximately 13 mm in diameter and 25.2 mm in length. The round bit of the lid can double as a flathead screwdriver for detachable handles like on the Canon A-1, which HAVE to be detached before you can change the battery. Handy if you don't have a coin with you. ⚠ Model tolerances are very tight. On Core One it prints fine, but if you have a worse printer or slightly larger batteries (I use "PoundMax" Batteries) you may have to scale the model (and perhaps the lid even more) up a little.

Batteries not included. :) Print instructions - Print at 0.15mm layer height, so the grip-ridges on the lid come out right. (They are 0.3mm deep)

- Print body upright

- Print lid upside down

- No supports or brim needed

- PLA works, but material probably doesn't matter
