EEEkit Hygrometer (Humidity Sensor) Through Screw Mount for Dry Box

thingiverse

This is a through-hole screw mount for an EEEkit Hygrometer (Amazon link). You can use this to attach a humidity sensor outside a container while keeping it inside. I designed this so I could easily see the humidity inside my sealed storage container that holds filament. You can quickly snap the hygrometer into the outer casing; it will stay secure because of tabs on the inside. It's not a perfect seal, but it's decent. I printed the casing in PETG. The package includes gaskets for both the inner and outer parts; these were made from TPE so they're a bit soft. A Fusion 360 .f3d file is included if you need to make any changes.
