Hygrometer Stand for Humidor

I made this stand to hold my Acurite 01083 Hygrometer at the perfect angle to see thru the top glass of my Humidor.

There are 2 versions. One version has slits and a recess to add a thin 40mm wide strip of steel sheeting (I reuse some scrap from gutters/fascia cladding), so the magnetic on the hydrometer snap to the stand. The other version is just a solid plastic stand.
