Magnetic hygrometer mount

Updated and uploaded version 2.

Version 2 was designed using Autodesk Fusion. It has a more streamlined shape and a variety of faceplates. Based on feedback, I've made a couple of improvements. Three base options are available, one with no space for tabs like the original, one with tabs at 11 and 5 o'clock, and one with tabs at 12 and 6 o'clock. The tabbed options help prevent the hygrometer from rotating and fit Bambu Labs and standard Amazon hygrometers. In addition to the tabs, I have profiles available for 0.20 layer lines and 0.08 layer lines. I've printed multiple parts for each option, and everything fits without issue. Lastly, there are supports for the magnet cutouts. They pop and pull out easily using flush cutters and a small pinch. Sometimes, they even stay on the plate. If you dislike supports, rotating the faces 180 degrees is always an option. The new bases and faces are interchangeable. The magnets' friction fit at 0.20 and 0.08, but a dab of superglue is always an option. 

I want to pass on a sincere thank you to everyone who has downloaded this model. 

Original description.

I recently purchased a Husky storage bin to store and keep my 3D printing filament dry. My goal was not only to protect the filament but also to monitor the humidity levels inside the bin. The humidity in my home generally ranges between 60 to 70 percent, which can affect filament quality over time.
 

The challenge with storage bins like these is that manufacturers typically don’t sell the lids separately, and I wanted to avoid cutting holes in the lid to preserve its integrity for potential future uses. Therefore, I explored alternative solutions for mounting a hygrometer to monitor humidity without permanent modifications to the bin. One option was to use adhesive backing, but I found a more elegant solution by designing and 3D printing a custom mounting bracket.
 

This bracket is my first design and was created using only basic geometric shapes (primitives) in Bambu Studio. The model includes slots for six 6x3mm magnets, allowing it to attach securely to the lid both vertically and horizontally, providing flexible placement options.
 

Although I printed the prototype in PLA for initial testing, it’s not suitable for use in high-temperature environments, such as filament dryers. The photo of the bracket in the dryer is just for demonstration purposes. My subsequent prints will be in PETG-HF, which offers higher heat resistance and better durability for this application.
