After years and many stolen Cache-Boxes i was now out of film roles :-( I know you can by them at ebay but why if you have a 3d printer? This box is not waterresistant but water safe if you use the ring to hang it in a tree. It is not for screwing but it has a long shaft so no water should come in if you place it vertical. It is a little bigger than a film box, so your logbooks should fit und you can place also a little pencil inside. Tip: Great looking if you print on part with glueing material for night caches ! :-)
