A small case to shield a Bambu XF-002 Digital Hydrometer and Temperature unit.  I needed something to hold a unit, shield it, and also keep the screen perpendicular to the floor, so this worked out well.  These hydrometer units and clones are also sold on Amazon and work well in this case.  Vent holes help equalize out the conditions inside the case while also allowing you to pop the unit out via accessing the locking tabs.  Its a simple two part press fit unit, and works well for what I needed it for.  One of these units will also fit into the front of a AMS unit should you want to monitor the humidity.  Simple, clean, and works!
