As allays please comment and leave photos if there are issues or even if there isnt issues I still like seeing people use my designs
So I recently started getting into airsoft and purchased a CYMA CM.126 M9 pistol, which comes with a small 500 mAh Ni-Mh battery which I had no way to protect without buying a larger case.
So simple idea, I decided to make my own and the simple idea became my normal slightly over engineered but still very well made design you see here.
There is space inside for only one battery of course but I may make other versions in the future that can carry more if needed, plus for a little extra security there is space on the inside edges of the openings to install a small 4mm by 1mm thick magnet that you can get from amazon in a pack of 20 for cheap.
Mine is only printed in normal Rigid Ink Blue PLA, but works great so far (photos should be attached soon)

If your printer is good enough I am sure you can print these open side down but that will need supports, so mine are printed flat side down as you would expect.
They are thin walls so infill makes not allot of difference but its nice to have for the grip and end sections.
