It integrates a standard mini round digital hygrometer/thermometer directly into the front face of the spoolholder cap, allowing you to monitor the ambient humidity and temperature inside your filament spool in real-time. Perfect for moisture-sensitive materials like PETG, TPU, and Nylon!
Update V2
I have updated the design based on a hygrometer model that features two side flanges. Special thanks to user @GregooryPEnn_1104574 for the feedback that made this update possible!
Key changes:
Added two dedicated slots/notches to fit the side flanges of the hygrometer.
Total socket diameter (including the flanges) is now 43.25 mm.
Reduced tolerances slightly to ensure a firmer and better snap-fit connection.
Compatible Hygrometer: You can buy the exact hygrometer used for this design on Amazon.
Key Features:
Real-time Monitoring: Keep track of humidity levels right where your filament rests.
Clean & Flush Fit: Designed with a smooth bevel for a seamless look and easy snap-fit installation.
Easy Printing: Optimized geometry that prints cleanly without requiring complex support structures.
Ergonomic Outer Ring: Features teeth/grip on the outer edge for easy tightening and removal.
Hardware Needed:
1x Standard Mini Round Digital LCD Hygrometer (approx. 41mm mounting diameter)
Compatible Hygrometer: You can buy the exact hygrometer used for this design on Amazon.
