Humidity/Temp Sensor Mount Sterilite 20qt Gasket Box

I purchased some very inexpensive humidity/temperature sensors from Amazon and wanted a way to mount them in my Sterilite 20qt Gasketed Storage Boxes for my filament. This is the solution I came up with. It's a snap-ring design that presses into a hole you cut, and the back snap ring holds it in place tightly to the box. I have included a drilling template to help with position and layout lines to drill instead of having to cut and crack the box.

Printing Directions: (see plate photo)

• Faceplate - placed flat and should be printed with the face on the bed. (you may have to free up the tabs gently with a blade if necessary)
• Ring - should be placed flat and printed with the receiver for the clips away from the bed.
• Drilling Template - has arrows that should face up when placed.  You can mirror the STL if you want to use the template to place the sensor on the left side of the handle.  

I had much better luck printing this accurately in PLA, but my photos are of the PETG example I printed and installed.

Installation Directions:

Place the template on the box so it's flat against the ridge on the left and where the curve of the plastic begins on the top.  I taped it in place to help mark and drill the four corner holes.  Once the four corner holes are drilled, I used a blade in the slots to mark the center of the drill points for the rest of the holes.  I used a 2mm drill bit to drill the holes.  A 15/64ths drill bit should work just as well.  1/4 should be ok, but I haven't tested.  The faceplate is large enough that it should cover without issue.  You will want to clean up the inside and outside of the hold as much as possible to allow the parts to sit flat, ensuring a good seal on the box. It shouldn't be needed, but you could always glue the backside of the faceplate to the outside of the box for extra sealing.

I use this with the Loose Bead Desiccant Trays I also designed (seen in the final installallation photo).

Good Luck and Happy Printing!
