Watertight Containers

Originally designed by myself as a water tight battery storage solution outdoors, I repurposed it as a generic water tight container. I have four sizes here, with approximate measurements. The 25mm id version with a 50mm height and 100mm height, and then the 40mm id version with the same selection of heights. The lid drops on and does a quarter turn to latch and an o-ring can be purchased from your local hardware store to get the watertight effect. The container is good in rain, humidity, fog and other outdoor wet environments, probably even boating, but only if not you're not expecting constant or frequent submersion. As far as ratings go, this would land about IP64.O-ring needed for the 25mm version has the following specs:ID 1-5/8"OD 1-¾"Width of 1/16". Could bump up to 3/32nd but it can be pretty difficult to open and close at that point without some lubrication.Industry #30 is the 1/16". O-ring needed for the 40mm version has needs to be at least 2 1/16", b
