Hygrometer frame mount for IKEA Samla Box and similar

I build this to check the humidity in my filament boxes.
Specially designed to fit on the site of the 22L Samla box from Ikea. But of course you can use the mount on any box you like.

The mount can holde a hygrometer with the size of 47x27mm (the cheap ones you can find on ebay and aliexpress)

btw. the boxes are painted with Krylon Camoflage in the color sand. To prevent the filament to get damaged by light.

If you interested in using this commercially, please contact me.
