Printed in PETG at .20mm slicing on a prusa mk3s+.
The battery is shaped for the larger EN EL-3e battery. But will still fit the more common and smaller EN-EL15.
It should fit a 70mm diameter by 3mm thickness O-ring if you would like to seal for water tightness.
It's a pretty tight fit, so I put a bit of krytox lubricant on the threads and screwed them on and off a few times.
I updated the lid to allow the base to screw in easier. At some angles the base was hard to screw into the lid.
