Description
This Seven Position Hygrometer Holder is an enhanced version of my previously released Swiveling Hygrometer Holder that locks into place in any one of seven positions to provide an optimal viewing angle. A magnetic version of the Base is also provided that includes two embedded neodymium magnets to secure the Seven Position Hygrometer Holder to any magnetic surface.
This design provides 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 other designs that I've seen, 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!
Assembly of the Seven Position Hygrometer Holder is illustrated in the following photo:
The provided STL files are intended to be printed in PETG.
PrusaSlicer 3MF files are provided for 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 Seven Position Hygrometer Holders seen in the photos were printed on an Original Prusa MK4 in various brands and colors of PETG with a 0.4mm nozzle at 0.2mm layer height with a 15% gyroid infill.
