You have to know the cheap round Chinese hygrometer with thermometer. You can find a lot of similar mounts, but none suited me.

The mount is bi-directional, just turn it and insert the hydrometer.

My design is based on a public model located in the OnShape library. You can find the link below of course.

I used a 10x10x2 mm neodymium magnet for sufficient attachment.

Print instructions:

• Material: PLA
• Layer: 0,2 mm
• Perimeters: 2
• Infill: 15%
• Supports: No
• Brim: Optionaly

This model does not require any special settings, more details in the attached 3MF file.

Part list:

• Printed part
• neodymium magnet 10x10x2 mm (or 10x5x2 mm [x2])

Assembly instructions:

The magnet is glued to the body of the holder with epoxy glue.

Custom modification:

If you want to modify the model, I am attaching the STEP file and a link to my OnShape.
