Mason Jar Lids for Hygrometer

Standard Mason Jar lids for use with Small circular Hygrometers. These are designed to fit mini hygrometers that are 1.7in/45mm in diameter (standard from my knowledge). You can find these commonly available online in 4 packs. File includes:Plate 1: Wide Mouth lid with shorter height (functional yet requires less filament)Plate 2: Wide Mouth lid with full height Plate 3: Regular Mouth lid with full height Plate 4: Regular Mouth lid with shorter height (functional yet requires less filament)How to installPop the Hygrometer in from the top until it clicks, and enjoy!These seal pretty well all on their own, but if you would like to improve it even more, the hydrometer can be glued into place by running a bead along the ledge before popping into place.
