Magnetic Hygrometer
thingiverse
I wanted to add a hygrometer, but do not want to drill extra holes on the airtight box. So I designed a magnetic bracket to hold clip the hygrometer onto the side wall or cover of the box. BOM: 4nos - 6x3mm magnetic 1nos - cheap circular hygrometer from Aliexpress or similar. (shop that I got it from: https://www.aliexpress.com/item/4000341246649.html?spm=a2g0s.9042311.0.0.26204c4dzG8oY5) No support is needed. The holes for press-fitting the magnets are very tight. I design it that way so that glue is not needed. Use is a G-clamp or mallet.
