Digital hygrometer mount for Sterilite container filament dry boxes

This simple mount holds an inexpensive rectangular digital hygrometer to the underside of a Sterilite container lid.  These containers are commonly used (along with desiccant) for filament storage dry boxes.

I keep a digital hygrometer inside every filament box, so I know when to recharge the desiccant.  I want to see at-a-glance the humidity inside the box, so I want to mount the hygrometer on the underside of the lid.  This mounting clip solves that problem.

I use these 20 qt Sterilite gasketed containers (affiliate link)

This retainer clips to the ridge along the underside of the Sterilite box lid:

Related models of interest

• Desiccant container (vase mode) 

Printing instructions

• .2mm layer height
• no infill
• minimum 3 perimeters
• poor layer adhesion may lead to weakening/breakage of the retention clips
  • use a strong material with good layer adhesion, or, orient the model 45 degrees around the long edge to strengthen the retention clips (see photos)

Mounting

• Insert the hygrometer into the printed part, with the digital face on the same side as the open end of the two clips.  ]
• Slide the open end of the clips over the reinforcing rib on the inside of the box lid.  If the clips don't hold tight due to manufacturing/printing tolerance, you can fold a strip of vinyl electrical tape over the reinforcing rib prior to attaching the assembled hygrometer/mount onto the rib.
