I created this Swiveling Hygrometer Holder to provide an attractive and functional enclosure for the type of hygrometer that is included with the Original Prusa Enclosure (and also available from dozens of vendors on Amazon, AliExpress, etc.). The holder can be placed on any flat surface and can be swiveled for the best viewing angle. Unlike most / all of the other designs on Printables, my design completely encloses everything except the display - allowing you to use any color(s) you like instead of the 10mm wide black / white bezel used in virtually every one of these mini digital hygrometers.

This holder is designed for hygrometers with outside (maximum) dimensions of 48mm wide by 28mm high by 11-18mm deep. The opening for the display is 38mm wide by 19mm high - which is intended to conceal virtually all of the hygrometer's bezel. And of course there are ventilation holes to allow proper sensing!

The provided STL files are intended to be printed in PETG and do not require supports.

PrusaSlicer 3MF files are provided for Prusament PETG and G-code files are provided for the Original Prusa MK4 - with all three components (holder, base, and cover) together as well as each component in a separate file (in case you want to mix colors).

The Swiveling Hygrometer Holder seen in most of the photos was printed on an Original Prusa MK4 in Prusament Orange PETG with a 0.4mm nozzle at 0.2mm layer height with a 15% gyroid infill for the base (15% to provide a bit of extra weight) and 5% gyroid infill for the holder and cover. The cover photo was printed with the same settings using Sunlu White PETG filament.
