A practical holder for up to three batteries for Olympus cameras, type BLS-50 or BLS-5, typically used in various OM-D or PEN models, so you won't have to rummage as much in your camera bag.
Printed very clean and great tolerances for my batteries. I printed 3. I printed them in pla; be gentle with the battery release, in pla its a bit fragile. Overall great fit and good hold for batteries. Two thumbs up!
